Tenshi kamo Shirenai

A series of standalone short stories, each exploring different scenarios and characters. One involves a girl who may or may not be an angel, while another features a boy living with an alien. A story recounts a boy's memories of a friend nicknamed Tsuru-chan, and another takes place in an underwater city. Additional tales include a boy listening to Chopin on the seventeenth day, a walk along a road leading to a shower, and an incident in Roppongi. Each story is distinct, with no connecting plot or recurring characters.
