Ryoma Takebayashi/Relationships

Father
Ryoma didn't like his father. Primarily because the lunatic forced him to learn martial arts and whacked the back of his skull with a baseball bat whenever he couldn't do anything perfectly. However, this was primarily the fault of Earth's God, who used Ryoma's father as one of many puppets to drive him crazy.

Mother
Ryoma loved his mother dearly. She was the only light in his dark life. After she died, Ryoma didn't have much to live for.

Gain

Lulutia

God of Earth
They never met, but said God wanted to turn Ryoma into a serial killer, treating him like an RPG character. For this reason, Ryoma had a living hell of life on Earth. He was given national level [God Trials] that were meant to make Ryoma crack and go crazy, from his father's abuse, the robbers' families painting him as a bad guy, and his abusive black company job. However, he endured them all, and God was forced to give him blessings as a reward, though he never revealed this to him. Eventually, the God got tired of Ryoma not even committing suicide and forced him to sneeze and get the fatal hemorrhaging by hitting the back of his head
