@flanman As far as we know Will was born into this world with no past memories of his former life. From the first chapter, it seems more like just a 'typical' reincarnation such as Buddhism or Hinduism. Lots of mish-mashed religious philosophies in this story though.
@friedtofu He does have some vague memories of his past life. It's mentioned, in the novel at least, and is the reason he tired so hard to lead a much better life this time.
I can't remember if it was implied or outright stated that the faint memories were like a gift from Gracefeel because of how much regret he carried in his previous life.
Damn in LN was already so sad, I thought I would be ready for manga.
Yes, next volumes story is weaker nowhere near to this 1st vol. This story of family is too strong, dunno how the author will compensate it.
