Ameliorate

Died as Geto Suguru, a once proud Jujutsu Sorcerer, who later became one of the enemies of mankind and the Jujutsu sorcerers that protects the non-sorcerer. He thought then that he reached his end, oh how wrong he was, for then he woke up as someone named Hajime, the eldest son of a poor family in an interstellar world.

He lived, gone through hardship, and learned to hate and love every single race that exists in the universe as he lived through his second life. He grew old, for living nearly a thousand of years with or without combining the years he lived in his past life. Hajime tiredly closed his eyes in his last moments, no smile rested in his lips, the fatigue of living for so long finally caught up to him. However, before he could finally rest in peace, he once again woke up as Geto Suguru, and finally reached the conclusion: This might be my punishment.
