"Brainwashing in our old world used to be a type of curse belonging to those who practiced witchcraft, as for its effects there numerous like changing the person memories or emotions or even personality."

"I have a level 6 resistance to it, would that explain such attempts?"

"I did notice you weren't acting like yourself like two times I think, even though I felt like you had accepted how things truly are and simply accepted your inner killer side..."

"There are two or maybe three memories that feel like vivid dreams, I don't think I lost any that I know of, and despite calling them dreams I do understand that it was no such thing."

"I haven't seen anyone around us that could cause a skill on you, from the behavior of the beasts they look kind of dumb to do that, perhaps the high-level monster could have something like that, but since it happened before he arrived that should not be the case."

With a quiet voice as I remember something I say, "I think it's the skills I got from my class..."

"Skills? Class skills? What's wrong with that?"

"When I appraised them they said it may change or affect personality in some way unknown to me."

"Yet you got them!?" She shouted at me worriedly and in a slight panic while also staring seriously at me.

"Yes, they looked the best of the class..." I reply innocently as I didn't expect something like this to happen to make Aurora's expression relax slightly.

"Well, I'd probably have gotten them as well if they were the best, good things always come with risks, after all, sometimes even high prices like..."

After waiting a bit for her to finish her words I question, "what do I do now about this brainwashing thing?" I tilt my head hoping that my sister has a solution.

"Well if you got a resistance to it, it'll be a matter of time till you can control yourself fully again, at some point you'll probably assimilate with the changes so just be yourself."

"What if I change into someone I don't wanna be?" I ask worriedly making Aurora smile gently.

She pokes my forehead," don't worry I'll always be there to look after you, I'm the older sister after all."

I smile and then I hug her, "thank you Aurora, you're the best."

She hugs me back with an evil expression unnoticed by me.

'With this killing monsters, beasts, and even humans will slowly become easier for Iris, truly a great class she picked.'

I collect the soul stones from the corpses while Aurora collects the weapons then I rest close to a tree.

2 hours pass and then I drink some water and eat some bread, recovering some of the fatigue.

"How are you feeling Iris? Do you want to continue or head home?"

"I'm alright just need to recover more of my mana how about you?"

"The slimes did most of the work so I still have enough plus I recovered an extra bit meanwhile."

With a low tone noticing a noise I speak," what's that noise? It kind of sounds like bangs on the ground?"

"Loud steps perhaps? More of those fat orcs perhaps."

I gulp down the rest of the bread and push it down with water, then I get up and hide behind a tree together surrounded by some bushes, and then Aurora transforms into grimoire form going into my arms.

After a few minutes, the steps get closer slowly and I start hearing different voices.

"What happened to these guys?"

"Goblin warrior there're more corpses up here along with an orc."

"I'm more worried about these three orcs it looks like they were pierced by something dying at the same time, not even I can slice through 3 of them with my ax and I'm a level 20 class warrior!" He shouted proudly with a slightly anxious tone.

"I don't know leader, but whatever it was must be around here still, so maybe we should camp elsewhere."

The goblin in rage shouts," are you saying we should flee from whoever did that!? What do you think our king would do to your body if he heard you spouting such nonsense?"

"You 10 look around see if you find any clues, I'll go up there check the rest of the corpses."

Aurora transforms back into human form and whispers to me, "a level 20 beast must be extremely powerful I believe the things we fought so far were at most level 3."

I whisper back to her," the orc I saw was level 5, I checked with an appraisal, and he already packed quite the strength..."

"Even then it took everything we had to defeat them, and they were injured from fighting each other."

"What do you suggest then?"

"I know you're a battle maniac but... I believe we should retreat here."

"Let's try something first before, go back into book form and climb the tree, and then transform back and warn me when a goblin is close to us, by waving your arm."

"Alright, if it goes wrong you'll go back home, you run without looking back."

"I will, I promise," I say while looking seriously making her feel somewhat assured.

After a moment she signals as a goblin scout is coming closer.

I hear his steps very close and the moment I see it, I ice coat my hand and place it on his mouth freezing his face pulling him to me.

Then I knee his stomach making him feel enough pain and the need to breathe and hold him long enough so that his air runs out while he does the best he can to struggle to no avail dying.

System: The title Assassination has been received.

Notice: 50 mana has been deducted.

Notice: 40 experience has been rewarded from a goblin.

Getting the idea she transforms into a book and floats without hitting any branches or leaves onto the next tree.

She transforms into a human and falls behind a goblin covering his mouth and neck with darkness.

If somehow voice would come out it would be sucked into the nothingness that is her element thus dying shortly after out of breath.

Notice: 40 experience has been rewarded from a goblin.

Another goblin approaches my position, possibly to see where his friend went and I repeated the procedure making him feel surprised and then suffocating to death.

Notice: 50 mana has been deducted.

Notice: 30 experience has been rewarded from a goblin.

I lose sight of Aurora and I peek carefully towards the rest of the goblins while holding my hair.

'I see 4 other goblins, I guess the rest is up there with the big one.'

'I create an icicle above one of the goblins without any of them noticing and imagine it piercing the head, as it does it enters through the nape then piercing his brain coming out of his mouth as it attempted to scream but it froze, making it look like he was about to like ice.'

Notice: 100 mana has been deducted.

Notice: 40 experience has been rewarded from a goblin.

Notice: The Class Skill Magic Control has been acquired.

'I can get skills from class without using points!? Seeing as I got some from the normal trees perhaps it makes sense, though it is fantastic, and perhaps I'm able to learn more things that way while saving points for things I truly want or need.'

'I imagine two icicles in different spots piercing the goblins, and then the first goblin falls on the floor flatly, followed shortly by the other two who get murdered by the skill.

Notice: 40 mana and 160 health have been deducted.

Notice: 30 experience has been rewarded from a goblin.

Notice: 40 experience has been rewarded from a goblin.

Notice: 30 experience has been rewarded from a goblin.

Seems like Aurora got the last one, I see her collecting the soul stones as fast as she can.

2 minutes later she runs at me, and we run out of the forest.

As we leave the forest I tell her, "it seems we can learn skills from class without spending points, we just need to do something that's worth the skill I guess."

"That's really good to know, I'll save my skill points from here on, also really good job on those icicles, hadn't seen you using those before."

"Thank you, I'm slowly being able to find new ways of creating offensive ice skills and using them effectively."

"Ice magic is all about creativity, one day you might even invoke 100 of those icicles into 100 different enemies."

"You truly do have gigantic expectations from me don't you sister? Imagine the amount of wisdom I would need as well as the magic control to pull that stunt off."

"Maybe..." she smiles kindly at me as we keep moving as fast as we can while laughing at each other.

"I wonder how much experience would we have gotten if we could defeat that big goblin."

"He looked like he'd kill either of us with one punch, not to refer the big ax," her words make me gulp down going into silence afterward as the reality kills my excitement.

After I get home I wash my clothes that smell of sweat, blood, and goblin odor, then I prepare a relaxing bath and hop inside the warm water.

"Ah..."I let out a satisfied moan filled with pleasure from the relaxing mood it brings me.

'That sure was an interesting adventure, if I had the whole mana I would've wanted to try fighting that level 20, goblin warrior.'

'I guess I really am becoming a battle maniac,' I laugh while taking the feet out and in of the bathtub playfully.'

'I asked Aurora to take the soul stones and our cards to the guild, I'd love to see Leonor's expression when she gets the 35 of them.'

'The good thing about being a grimoire is that she has infinite energy and never gets tired allowing her to walk endlessly if she wishes to do so.'

'Meanwhile, I overexert myself often to collect all the titles I can, in the end, the more I get the stronger I get like my sister said, good things come with a cost, and for me, that is energy and time.'

I finish the bath after a while and head to the bed of my room to get some rest as my muscles are sore and currently a bit relaxed.

※※※

Goblin Warrior Perspective minutes after the girls left the forest after assassinating the goblins.

Filled with sadness...

"My son, my son is dead," the warrior shouted while lamenting and crying as the rest of the goblins that were with him lowered their heads in respect."

"I spent a long time training you to become stronger than me to lead your own group in the king's army."

"All for naught, all because you were killed mercilessly for no reason..."

Filled with rage...

"I don't know who did this but I'll find them, I'll catch them, I'll torture them, I'll kill them."

The nearby goblin patted the big warrior's shoulder sympathizing with him as his brother too was killed.

"Ah!" He pushed the goblin away with the backhand on an arm swing making him fly 10 meters backward.

"I cannot control this rage I must exact revenge otherwise I'll fall apart, I'll go mad," he shouted fiercely as he gripped his hands tightly while his body shook, and the veins slightly popped out from the fast circulation of the blood caused by his emotions that sped the heart rate up.

Filled with despair...

"This bottomless emptiness must be filled with the blood of the one who murdered my son."

"May fate allow us to cross paths, may the god of chaos hear my one and only prayers."

"May the almighty God bless me or curse me with his gift as he did to our ancestors in times of war."

"May he take my soul but in exchange allow me to exact my revenge, on the one who killed my son please I beg you oh lord."

Despair, rage, sadness... Chaos.

In his mind, a message resounded.

System: The god of chaos has taken notice of your pleas goblin warrior, and feeling amused the class Berserk has been unlocked for you.

He wiped his tears off and changed classes, then he knelt further while raising his son in the air.

"I'll forever be in your debt oh great god of chaos for allowing me to become a goblin berserker," the ones around could feel the pressure he emanated from changing classes.

He stood up and picked the goblin he pushed out of anger, carrying him unconsciously back to the goblin kingdom while being followed by the rest who remained quiet.

For a moment he looks back and memorizes the rest of the icicles laying on the floor melting slowly, then he leaves knowing that his lifelong enemy will possess such an element.
