Scathach doesn't use any weapon, she just accelerates towards Issei and only use her bare hand to punch, a pure physical attack. Her Red colored pupil that seems can see through soul which shine aggressively, then she suddenly arrived in front of Issei instantly.

Realizing the danger that suddenly arrived in front of him, Issei fighting instinct kicks in and he tried to dodge the incoming attack but to no avail. Then his body hits the wall.

BANG!*COUGH*

He coughs out a bit of blood from his mouth and he couldn't help become confused at what just happened because even though he already avoided it. His body was still hit, just what exactly happened?

Scathach - Thinks very strange? That was my Ougi(Secret Technique). If you understand some Celtic myths, you should remember the special skills of Magic Spear Gae Bolg. Can master this ability so far is only me, this is the spear ability trait. Its true identity is that of a reversal of causality, in which the spear is released after the outcome of the spear hitting the heart. And since it is an attack based on the outcome, it is considered impossible to evade. What I must teach you are this technique, how far can you comprehend this skill is totally up to you! You must try to use it even without the spear itself and apply it to all of your attacks, don't think I can do it only because I have the spear. The spear special trait can only be activated once you totally comprehend the trait itself, the spear can only show its full potential if the holder itself is capable!

Scathach comes closer to Issei then proceeded to pinch his chin gently and make him look up to her then she says "However what I wanted to say is this, I have never lost a close quarter combat, and as for a long-distance fight... I have a ranged technique, wants to defeat me is very difficult. So do your best to not disappoint me, because I'm waiting for my payment. Issei Hyoudou!". Then she gives his lips a quick peck.

Issei once more becomes stupefied because once again he got kissed without his consent, well at least it's not a guy who kisses him or he would have totally snapped. But it still pisses him off that he once more got harassed by the opposite gender even though he's supposed to be the man here, but he knows he can't do anything about it since she's way stronger than him at this moment so he can only hold it in... for now.

Scathach then let go of his chin gently and walk away facing the opposite direction. But her cheeks are mildly blushing and she got a bit of goofy smile on her face whilst thinking 'Hehehe~ finally I have my first kiss!' her heart keep fluttering knowing she finally lost her first kiss to the man she approves of.

Issei got up and scratched the blood under the corner of his mouth... if he could grasp such strength. So long as his attack hits, then he can be considered winning already.

Issei - Interesting, please teach me this technique. Shishou! I promise I won't disappoint you.

She gets herself together then face him back and says.

Scathach - Very good. Since you have set firm resolve to study this then be mentally prepared, I will not treats you gently, I will be teaching you strictly! Either you defeat me, or I will kill you! I don't need a weakling as my students('or as my lover' she added in her mind), so be prepared!

Issei - AH! I won't have it any other way regardless!

Then her body rapidly vanishes, then she appears behind him, a leg whip struck to fly Issei once more, then she coherently kept attacking him, like a Sadistic Queen! But Issei never even once argue nor protest about it he just keeps follow through her harsh training and absorb every bit of her teaching like a sponge.

Whenever Issei promotes a strength and skill, Scathach also adjusted her technique and strength, and its always exactly just right. The condition and angle of the beating down have not changed from the beginning, he's always the one who gets tossed around until he managed to comprehend the basics of the skill. Now he could execute it through his normal punches but not strong enough to beat her but don't think its a weak attack.

If anyone else got hit by it then he/she won't get away unscathed.

And each day he spent training. His Dragon trait also started to awakening, he got stronger, faster, smarter at an alarming rate that she even thought at this rate he might just surpass her soon enough. His comprehension skills also keep growing and she really has to admit he's by far the best genius she ever saw in her entire life maybe even more than herself because from what LD told her he should be quite young around the age of 17 by human year and he's also a former human which she finds quite nice because she's also a former human before transforming into a Divine Spirit.

When she finds out a bit of his past from LD she was furious! She might have just went to his world and annihilate everything that got in her way to find the ones who betrayed and make his newfound beloved hurt like that.

But thankfully LD stopped her from doing so by telling that's for him to judge himself not her or anyone for that matter. So she relent it for now but she would make sure if by chance she got her hands on them, she will make them know what it means by Might as well be dead rather than be alive! Which LD totally agrees with, but she told her that she wants to get their souls because she wanted to put them into limbo. After that, both of them are acting like sisters which baffles Issei because before they kinda always have a disagreement between each other, not that it concerns Issei that much because what's on his mind right now is only to get stronger.

One day LD asked Issei for a favor, which he agreed to as long it doesn't go against his principle whatever they might be other than the original request from her that wants him to be hers. What she asked are for him to give her a name because she tells him she doesn't like her old name and has forgotten about it because of the betrayal, so Issei thinks about it for a bit and agree "If you're okay with me giving you a name then..." He asked her once more. And she responds with a happy and seductive tone at the end "Of course I agree, especially if it's given by you. Dearest~!" which makes Issei blush a little because he still doesn't get used to that nickname given by hers.

"...How about Semiramis?" He offered, which she finds quite interesting considering the legend behind that name and she gladly accepted it because it does resemble her past because she herself often poison her enemy to death just to see them suffer. And just like what she did to her so-called "lover" who betrayed her before, slow death by poisoning.

So LD which goes by the name Semiramis now is happy that she finally succeeded her plan of making her new beloved giving her a new name, she kept humming in a happy tone the entire day that makes Scathach wonders what make her so happy in the first place, and when she heard the reason of her happiness. She totally becomes jealous and regrets of not being able to have her dear apprentice give her a new name because she already has one... But she's also happy that Semiramis got her wish because they both have already discussed among themselves about their newfound beloved.

At first, she totally freaks out that Semiramis knows the real reason why she's looking for the perfect candidate as an apprentice. But she calms down when she heard Semiramis past and felt sorry for her too, then when Semiramis proposed the harem plan to her she was surprised but not too much because she finds it totally normal for a man of his caliber to have multiple wives, heck even when she's still a human Queen she kept being told to build a harem for herself by her ministers and generals.

But she was never interested in that stuff because even though she likes handsome men just like other normal girls she doesn't need an empty vase. What's the use of being handsome when they are weaker than her? Even she wanted to be protected by the one she loves sometimes.

Unbeknownst by Issei, he will get a harem whether he likes it or not, of course by the time he found out about it, it will be all too late because he will already have a big amount of women following him around everywhere he went. Not that he minds it that much later on...

-A month later-

Issei and Scathach can be found sparing like usual in the training ground but there's something different... They are fighting on equal ground! Not like the usual where Issei got tossed around by her. Even though they only did hand to hand combat at the moment but you can see they are enjoying themselves especially Scathach because the man he loves might be able to fulfill her long time desire sooner than she thought. He even gains mastery on her Eternal Arms Mastery and can use any weapon at the level on an expert, not a grandmaster level but still quite amazing considering she only teaches him a little about it. But his hand on hand combat is on par with her.

Issei also enjoying their little spar because he can tell he is stronger than ever before now and the control of his Life and Death aura reaches to expert level and he can gain mana even faster than before just by absorbing a bit of life force around him and he can also touch and see souls now just like Semiramis, and he could consume the soul itself if he wishes so. But not recommended by Semiramis because it's a bad thing to eat a soul because it can corrupt his own soul purity and the fact that most of the souls around her domain are evil souls cemented her suggestion even more.

Not that Issei wants to eat souls in the first place anyway because in the end he's a former human, not some mindless beast so the idea of devouring souls is disturbing even if by devouring souls he can get their skills and experience, in the end, it's not his own power so he detests doing so. This just make both ladies fell even more at him because most people would choose this shortcut.

During this month Issei opened up even more to both ladies, Ddraig is still on the process of making his new body so that's quite sad for him because he does miss his trusted partner ( Unknown to him when 'Ddraig' finished reviving himself they won't just be partners in name, but partners for life~ (͠≖ ͜ʖ͠≖) both in body and soul ). Issei told them about his past, about his first date with Raynare, to his revival by the woman he thought the love of his life Rias Gremory, and till his confession to her during the rating game, he fought for her.

Both Semiramis and Scathach listened attentively without uttering a single sound because they want to know the past of the man they come to love, and when they heard his first betrayal by this woman called 'Raynare' they almost blew up but hold it in, but Semiramis made a mental note to get her soul when she pays a 'visit' to Hades domain. For 'Research' purposes of course~. They both also noted the name Rias Gremory in their mind but they never heard of Gremory household before or maybe they just forgot about it because its been so long? Well, they never really care for some weakling in the first place.

Issei stopped telling his past till then but both women are not saddened at all...

If anything they are happy they are closer to finding the truth about their beloved past and when they do find it... Hohoho~ there will be the time where they wish they never born, not like they gonna kill them straight away. It's still up to their beloved what happens to them, but they sure will make them suffer when the time comes.

He also smiles a bit more nowadays at them but always has a distant and melancholy look when he's alone. They both promise to make him the happiest man when they saw his looks, and Semiramis started to search for potential worlds that can make him more relaxed so he could forget about his past because she knew just by staying here it won't help much with his case and he needs to experience the new environment with that.

Scathach, on the other hand, started sneaking into his bedroom and keep stealing kisses when he's asleep using her Perfect Stealth Enhancement she has, but Semiramis finds out about it and scolds her for not sharing.

So they both take turns kissing him without his knowledge, Semiramis cast a silent sleeping spell so he won't wake up and Scathach hides their presence just to make sure nothing went wrong. They even went as far as deep tongue kissing and kept exchanging saliva, and at one point they came just from the kissing session they had and both women are in bliss because of their secret night activity.

At one point Scathach wanted to take it to another step but Semiramis prevents her saying its better doing 'that' after they have his consent, not like she's the one to talk because she kept stroking his junior down there during their kissing session and oh how ecstatic they are finding out the 'size' of their beloved down there. It has the perfect length and the perfect thickness. Just by looking at it they got hot and bothered down there, it's by far the biggest they have seen in their entire life combined...

Issei keeps waking up feeling weird because his mouth always feels sore when he wakes up. And he feels ashamed that almost every time he wakes up he got a white stain on his pants thinking he had a wet dream or something and blame it on his Dragon libido, he cast cleaning magic to remove the stains every time this happens. And he finds it suspicious every time this happens the girls face for some reason are sparkling and beaming with satisfaction but shrug it off thinking its nothing that concerns him.

When Issei doing a handstand with 1 finger with a bunch of weights on top of his legs, Semiramis called him to talk about traveling to different worlds...
