On one night were the winds howl and in the distance were screams of pain are heard there stands a boy with crimson hair and dark blue eyes, he was smiling whilst standing on top of a roof covered in blood

Let's go back 3 hours before this took place

The boy who's name is Riki shindoma was sitting on the roof of a building with a boy named taro and a girl named Yumi

They were talking about what to do after school when suddenly the sky turned red and a black whole came from no where but no one was sucked inside, whilst the trio was panicking about getting of the roof they froze in place and heard a voice stating

Masked figure : this world is too boring, let's make it more fun

After that statement they began to move again but before they could get of the roof they saw monster, ghost coming out of no where. The trio were stunned by fear Riki who knew that they could die by just standing around shouted to his friends to run but it was too late because taros head was ripped of infront of them and eaten by a monster.

Before the monster could kill them as well they started to run to their class when they reached there they saw that every one was killed and the only thing that remained were their life less bodies, by seeing this yumi started to scream in fear whilst she ran away when Riki heard her noise he said

Riki : stop yumi the ghost are going to find you

She did not listen when Riki heard silence he went to check on her but saw her body on the floor he started to shed tears knowing that both of he's best friends are. Now dead he was crying loudly but then stopped when he heard shouting down the stairs, when he went down the stairs he saw a man shouting at a katana by saying

Unknown man : work you damn thing I bought you with a lot of money so do not screw with me

When he saw me he put the saw down beside him and went to and asked

Unknown man : kid are you ok

Before Riki could reply a wing less dragon started to spit poison at the man and before he could attack with his sword he got poison on his face and it melted off, with this horrific ciné Riki was left face to face with the monster and the katana between them.

Riki ran and dodged the poison and picked up the weapon and blocked an attack for the creature before Riki could defend himself, time stopped but not for Riki only around him when he turned around he saw a woman with gold hair walking towards him whilst saying

Unknown woman : you seek vengeance yes, you wish to make those who did wrong to you to suffer yes, I will give you the power to make it right

Time resumed with Riki still facing the wingless dragon but in an instant Riki cut the dragons left leg of but it regenerates it but the next moment Riki is behind it and the dragon is turning into light because Riki cut it multiple time and shattered its core

Riki with a sad look went to the roof with his katana and looked at the moon and said

Riki : I wish you guys were here too

Riki the was spotted by a large number of monsters and smiled whilst saying

Riki : give me your best shot
