The northern forests are located in the northern part of their kingdom. Travel there does not take a long time. It just takes a few hours to get there depending on the situation. After making the preparation like a sword, potion, and more Aoi and her twin brothers go there by using horses that were lent by the bar owner.

The sword that Aoi brings with her is Tsurugi. This sword is shaped like any ordinary great sword but has a blue diamond in the middle. This sword has been with Aoi during her childhood. They said that this sword is only choosing the guardians as its owner. After the last owner abandoned it, they are no one capable to swings this sword again. This is because of the curse that has been placed there by the moon to make sure the only chosen one can use it. So, Aoi is the chosen one by the moon to be the next guardians.

After half an hour, they finally arrive in the north forest. They arrive there in the late evening. They feel strange because usually, this place is full of animals. This is because out of all of the places in Elf Forest, the north one is the one that provides with a high food for animals. However, today there was not a singles animal here.

After binding the horses to the tree and researching around, they finally found the troll base. The base is very large and has a wood fence surrounded it. In the base, it looks like a few houses that are used as a place for trolls to protect themselves from any attacker. It also uses for stored their weapons. There are also a few trolls that patrol around to defend their base from any attacker. After investigation, Aoi and her twin brother decided to hide in the bush not far away from the trolls’ base.

"So, the reasons why they're no animals around here are because of these trolls. They drive away all others animal to stabilize their base here. Unforgivable. “Aoi said to herself.

Aoi holds the knob of her sword which she slipped at his waist and tried to lunch a surprise attack. However, before she fully takes out her sword, her hand was stopped by Sora.

"What are you want to do, onee-chan?" Ask Sora with a serious face.

"I want the trolls to pay back for what they do to our forest."

The trolls have really disturbed the stability of this forest. Driveaway all the animals here only will cause a lot of animals to lose their place to refuge and hunting. Without hunting, they cannot eat and lastly will die out of hunger. Not only that, they also will turn wild animals and enter elf kingdom territory make a destruction.

"Wait…we cannot go and launch a surprise attack like that onee-chan. Looks!" While pointing his index finger in a certain direction.

Aoi looks at the place that Sora point and saw a few creatures that look like an elf, but they don’t have long ears. The creature body was tied up with a rope on the pole and they are not moving at all. Maybe all of them was fainted. From the situation there, it looks like the troll is trying to cook them alive.

"What kind of creatures is that? They look exactly like us but with short ears." Ask Sero with a clueless expression.

"I don't know… but as long as they have those creatures as a hostage, we cannot launch a surprise attack. We must wait and plan our strategy first. We don't want that creature to hurt right?"

Aoi realizes her mistake. Even that creature is not an elf but there are also living things. And every living thing has families and friends that they want to return to. Aoi understands their feeling because Aoi also once felt lost. Aoi lost its mother 2 years ago, and that feeling still touching her heart. She doesn’t want anyone to feel like she ever felt again.

"So, what are we going to do now?" Aoi questions Sora because Sora is the one that always comes out with the idea.

"Come here."

***

At the entrance of the troll base, there are two trolls was patrol around while holding a spear in their hands. While patrolling the two of them are talking about something.

“Do you hear about the news?” With a happy expression.

“What is it?” Excited to hear.

“I hear that our boss has captured some human.”

“What…human!!” With a shocked face.

“Yeah”

“What are they doing here? How can they enter this forest?” Still shocked. He cannot believe a human can enter the Elf Forest.

“I don’t know man… but when the boss returns from hunting before, he had caught some of the humans with him. That why he asked us to patrol around to make sure there are any outsider will not come here. If another creature especially Elf saw there are humans in the Elf Forest, the sudden war will erupt.”

“What? Why? It’s not like that our enemy is that strong? They are just a mere human. They are very weak compared to the elf or other creature.”

“Yeah! you right. Our enemy is very weak compare to other creature but…” Change his voice to serious “Our boss said that never underestimate the human. Even though they are weak, but they can keep up with the elf and vampire in combat and magic. They also can create their own empire. I also heard the news that human territory is wider compare to elf and vampire.”

“Is that true? I thought that just a rumor.” With a shock face.

“Yeah, that true, human is the scariest race. With their knowledge and creativity, they can create weapons with the combination of magic and technology and surpass any other creature. If there were suddenly being a war, I think that the human is the last race I want to fight.”

“So that why our boss told us to always precautions with the human. But why is the boss want to cook and eat the human alive?”

“Don’t you know that human meat is the most delicious? Compare to any other animals, human meat tasted sweet and juicy. They're also a rumor that said if you eat human meat, you can take over their knowledge.”

“If that true, then we don’t have to be afraid of the elf anymore. Elf always disturbs our territory and drives away us from this forest just because we kill the animal here. They have been causing us a lot of trouble, right?”

Without his friend's reply they suddenly stop their talking when a suspicious person was walking slowly into the main gate with a hood cover her head.

“Who are you?” asked one of the trolls, but they are no replies.

This person was ignored that question and slowly passing through these two trolls without looking at them like they are invisible.

“Wait… who you are?” Ask him again while holding these person's shoulders to stop her.

Stabbed!

Without a reply, suddenly this person stabs one of the trolls that hold her shoulder to his heart with her sword. The troll falls to the ground with the blood flow around his chest. With panic, another troll tries to attack this person using the spear that he caring with him, but this person quickly dodges and launches a counterattack on him. The troll is trying to dodge that attack, but his body cannot move. It felt like his body has been locked by certain magic that makes him cannot move. Finally, the hood person swings her sword to the neck of that troll and

Splash!

In the blink of eye, the head was separated from that troll body. The head was rolled over in the mid-air a few times before it falling to the ground.

The hood person splashing the blood at her sword to the ground and open the hood. This person is Aoi.

After killing the trolls Aoi and Sero dragged the corpse and hiding it in the bush before.

"So, what we gonna do next?" Ask Aoi.

"Now I want you to act as a decoy and make chaos at the entrance while I and Sero will using the transform magic to transforming into these 2 trolls." Said Sora while checking the dead body of the trolls that Aoi kills." While you take their attention, we will be trying to sneak into the main base and released the hostage."

"What? Why was me to act as a decoy?" she not satisfied with Sora's decision.

"This is because you are the strongest one in this group and I need Sero to used his transform magic to me." Sora trying to explain to Aoi. "Moreover, we don't want the hostage to be injured because of your stupidity again."

Sora tried to tolerated with Aoi. Sora knows that every action in this world will come with a result. The action without a good plan will come out with unsatisfied result and make the consequences that they must face later. Not only that, they will have to face with a very big trouble if the plan failed. That why it is important to think a good plan first before doing something.

"Fine, but make sure two of you save the hostage quickly because I can’t be patient for too long. If you are late, I think I will kill all of them by myself." said Aoi with a sullen tone while turning around and walking away.

Sora and Sero just looking at Aoi's action with a speechless expression. "Huuuuh...." Sigh Sora while clapping his head." Still no change." he said to himself. Even at that age, Aoi is still not mature at all and sometimes acts like childish. She always against the plan that he made even it for benefit of all people. When she will change and be like other people.

"Just leave her like that. Even she is like that, but we know that she is the best sister in the world," said Sero while holding Sora's shoulder.

Sora turned his head and looking at Sero's face. He glaring at Sero's eyes and from his eyes, he can see that Sero loved for his sister is bigger than anything else.

“Yeah, you right.” He returned his smile. He has to admit it, even Aoi's personalities are a little bit rough but the two of them know inside her, she has the kindest heart. That why she still wants to save those short ears creature even though they don't have any relationships with her.

"So, this is the trolls that we will transform into." Sero moves to the dead body of the trolls and begins chanting the transform spell.

"Wait...." Cut Sora with a serious tone. "That is not only the plan."

“???” Sero confusing.
