A Psychic Demon Slayer

Saiki had a happy life. He died at the age of 43 due to an explosion happening at his brothers laboratory which is his work place. If he was one step slower, then the whole England would have exploded. He just forgot to protect himself. Accidents happen.

Saiki already knew that he was dead but he woke up. He woke up as a baby in another world and another timeline with no advanced technology.

His house in that other world looked broken and old. He has a few other siblings too. He now has white hair and yellow eyes.

It seems like he cannot use his powers but their still there. The feeling of his powers still being there but cannot be activated is irritating. It feels like something is missing. This is the first time that Kusuo doesn't have his powers but wants to use them. Use them to get his family away from this place. It is very similar to the slums. Even their father abuses them.
He couldn't use his powers until... One day. It was the day he found out that his new world is much more dangerous than he thought.

In his old world, he was called Saiki Kusuo. In his new world, he is now called Shinazugawa Kusuo.

In the new world he arrived in, he is going to meet someone. Someone similar to him. Someone also not from that world.

He is a transmigrated person that came from another world similar to his old one.
