夏飢聲（なきごえ）

First-person horror adventure

夏飢聲（なきごえ） is a first-person horror adventure set in the world of Kyoso Musebiya, a haunted house attraction created by Obaken. Ren Yuki, a young man with an illness who has lost hope for the future, wakes in a mysterious mansion after following a glowing cicada that appears amid a cry in his hospital room. The mansion has no exit, and a passage leads underground.

Hunger underground

As Ren goes deeper, an abnormal hunger grows stronger. He reluctantly eats glowing cicadas found underground to survive. Each one brings him memories belonging to someone else, and those memories help reveal the secret of the supernatural entity wandering below.
