By some ill fortune, Hikaru died in a traffic accident. He was in heaven standing in line, waiting to be judged, when he took an unexpected request to transfer his soul to a person in another world. He received an ability called Soul Board which he could use to allocate points to Skills to make himself more powerful.
But there was a catch…
「I want you to take revenge on someone for me within an hour. If you don’t, I’ll destroy your soul.」
To pull off the task assigned to him, he poured all his available points to the Stealth skill tree.
This is a story of a boy who specialized in Stealth. With his skill trees as weapons, he would demonstrate his unrivaled strength in another world.
