A collection of short stories by Otsuichi which resembles a Zoo with its many short stories covering different topics, settings, and genre.
Identical twins brought up in the same household where one is treated like dirt and the other a princess.
The last man on the planet builds a robot to bury him as he muses about his own impending doom.
A family tries to find their father's spare blood as he bleeds to death after having been stabbed by a kitchen knife.
And many others.
Whats great about it is :the mc palpable personal growth without suddenly becoming another person, very fair and balanced power system, side characters are very interesting and i think its cool how u can draw a personality chart about them by comparing their reactions and tidbits of their lore across multiple loop iterations.
Cons: as someone else said it definitely needs some side stories, i personally didnt like what happens after the ending, i wanted more closure with more side characters, i personally wouldve liked more than just tidbits regardings the cooler characters.
