『C団地』第1話 Optical Illusion（めのさっかく）

Kimi Shirokado is an eccentric girl whose complaint about the heatwave leads to her and the senior residents of Housing Complex C to find strange things while getting an ice machine in a secret storage cellar. Over the course of the next few days, Kimi befriends a girl named Yuri Koshide whose family moved into the housing complex along with mid-eastern interns. Later, Kimi brings Yuri to the storage cellar where they find disturbing drawings belonging to a Hikikomori named Hideo. They return Hideo’s pen to him and he draws a cute picture of the two. Kimi comes to invite Hideo the next day for shaved ice and accidentally steps on his anime figurine upon noticing his bedroom door open, finding a large pile of moss inside.
