Just another reincarnation story. Well hopefully not 'just another', but there is a rebirth and a new world so lets just go with it and not take things too seriously. Well thats it I suppose. If you want a real preview read the prologue. Thats what it's there for.Ah, by the way. Kaizen is continious improvment, so don't let the beginning fool you and expect the MC to be all-powerfull by the end of it all.
