Zetsurin de Kedamono na Shinyuu ga Ore wo Dekiaishiteita Nante Hajimete shitta ga!? Nyotaika shite kara Mainichi Idaki Tsubusaretemasu

After finally escaping the grueling demands of an exploitative workplace, Aoi Tsurumizu finds his life completely upended when a devastating fire destroys his home. Wandering the streets in a daze, he narrowly saves a stray cat from oncoming traffic and unexpectedly crosses paths with Kei Hiyama, his strikingly handsome best friend from high school. Noticing Aoi's injuries, Kei insists on bringing him back to his residence—a sprawling unit inside a luxurious apartment building. It is there that Aoi discovers his old friend has risen to become the successful president of his own company. Moved by Aoi’s tragic circumstances, Kei warmly offers him a place to stay. As Aoi relaxes in the bath, he reflects on how Kei remains just as gentle and caring as he was during their school days, though he cannot help but feel a pang of envy toward the women who must have enjoyed Kei's attention over the years. However, his quiet contemplation is abruptly shattered when a mysterious light suddenly envelops him, triggering an inexplicable physical transformation that leaves everything uncertain.
