Hatarakanai Futari (The Jobless Siblings)

[Diluc]

A slice-of-life story about two siblings, both jobless shut-ins.

Haruko is a teenage girl who shares with her brother a love of laying around the house in sweats, watching television and playing video games. Her brother has a few friends, but Haruko has a lot of problems with social anxiety. The two of them pass their days happily playing together, though their mother worries about how she's going to get Haruko to shape up enough to find a husband.

Sorry incest shippers this is not incest
But the story is totally depressing about two hikikomori siblings, the sister anxiety level is same with Tomoko from watamote, rather ship with her brother you ought to ship her with someone else so she can get a better life.
Having her go incest route only making her life more miserable.
