Keeping a Diary in the Apocalypse: Heroines from Across Anime Go Bad

Su Yang is reborn at a school in Takao City on the eve of the apocalypse!

There are thirty days until the apocalypse breaks out, and he binds himself to a Diary System!

Writing in the diary earns all kinds of rewards.

Saeko Busujima, a senior he has no connection with, actually approaches him of her own accord!

Utaha Kasumigaoka, the sharp-tongued girl from a hundred miles away, even transfers to his school with her family!

Saeko Busujima: "The protagonists of this world are actually Rei Miyamoto and Takashi Komuro?"

Utaha Kasumigaoka: "Did my appearance disrupt Su Yang's plans?"

Rei Miyamoto and her mother: "We both have such tragic endings? No way, we have to get on Su Yang's good side!"

P.S. An apocalypse harem novel with no saintly heroine!
