Young children living in the forest... they have a secret.
However, there were children living in that forest.
Those children lived without parents or any other adults. On the surface, they look very weak and worrisome, but in reality, those children are... 「Monster Hunters」.
They hunt monsters using their own unique weapons received from the Monster Hunter Association. At the same time, they must not be caught by visiting adults, and they have to stop monsters that pretend to be human.
'...I told you, that's just a mushroom.'
He is a young 12-year-old boy. He plays the role of looking after and managing the kids*, but in reality, he's the one who causes more trouble.*
A child with orange hair and distinct orange eyes.
His weapon is a magic pistol. When he shoots bullets imbued with magic, the target hit by the bullet suffers as if they were struck by that magic.
A bright and sly boy. He is very curious and causes a lot of trouble. However, his heart for worrying about his younger brothers never changes. He is a bit of a coward.
'It's okay, it's okay~! Koyo, come with me!' "Should I..?!"
He is a young 7-year-old boy. He is the youngest, but he actually ends up taking care of Nino more.
A boy with grey hair and red eyes.
His weapon is a large hammer. He can use a hammer larger than himself to crush enemies.
A bright and brave boy. He is curious and a troublemaker who rarely changes his mind once it's made up, but he follows his older brothers well. However, he often causes trouble with Nino. He is a lit-tle bit of a coward.
'Otto-nim, come quickly! I'll go with you!'
He is a young 9-year-old boy. He is smart and helpful, but he has some eccentric parts.
A boy with purple hair and soft purple eyes.
His weapons are a grimoire and a dagger; he can use magic with the grimoire and attack with the dagger.
A smart and kind child who helps others well, but... he is weak at English and has some eccentric sides. However, he frequently worries about his younger and older brothers. He is very... cowardly. (That's why Iro says he'll go with him.)
'Iro... are you sure it's really okay...?'
He is a young 8-year-old boy. He seems calm and quiet, but in reality, he's said to be a bit of a psychopath...
A boy with white hair and pale sky-blue eyes.
His weapons are chains and a scythe. He can subdue or bind opponents with the chains and attack with the scythe.
He looks calm and quiet on the surface, but he is more curious and has a scary side than one would think (almost like a psychopath...). However, he likes his hyungs and Koyo, and he goes with Otto whenever Otto is scared. He has al-most no fear.
'Hey, why are you like that~ We can be a little close!'
He is a young 11-year-old boy. He seems blunt and quiet, but he has an eccentric side. He is the one who usually stops Nino from causing trouble.
A boy with black hair and vivid green eyes.
His weapons are a repeater crossbow and an impact hammer. He can attack opponents with multiple shots and swing or strike with the hammer.
On the outside, he is blunt, cold, and seems difficult to get close to, but in reality, he is said to have a very eccentric and somewhat cowardly personality. He cleans up the messes made by Nino and the other kids. He is more cowardly than he looks.
It was a peaceful and quiet morning in the birch forest. The children woke up and were chatting in the living room, playing and talking together.
[The Forest Altar] is managed in rotation by the people living in this birch forest.
Long ago, to save her grandmother who had been eaten by a werewolf, a young girl wearing a cloak made a wish in the forest.
This was because a werewolf's skin was so tough that it could never be cut by human strength.
A brilliant light descended upon the werewolf, and the werewolf spat out the grandmother before vanishing into nothingness.
But werewolves likely still remain.
On nights when the full moon rises...
You must not be outside when the wolf howls echo. For you will not be able to resist...
Each of the children wears a cloak. Nino's is orange, Koyo's is red, Otto's is purple, Iro's is sky-blue, and finally, Robo's is green. Since the children must not have their identities discovered by others, their weapons are stored in a basement hidden in the house.
Appointment Letter
According to the screening criteria of the Monster Hunter Association, we appoint these five brothers—Nino, Koyo, Otto, Iro, and Robo—as the monster hunters in charge of the [Wolf Forest].
On the day of the full moon, please hunt 3 monsters and send items to prove this by mail.
We will not spare continuous resources for those who work for the safety of the forest.
Monster Tracking Methods
Finding the location of a monster is not easy. It is especially difficult in the forest. Using a method to [lure] the monster is the most ideal way to operate.
Hide your identity and expose a weak appearance. Identify the habits of nearby monsters to lure them. Watch for people walking in the forest at night. Hang something that gives off a very strong scent of blood.
