[This is a nontraditional secret identity novel] The "Book" on the Beast route watched its beloved Dazai take one step after another toward the abyss, and felt utterly despairing.

Protagonist: ...Have you never heard of dying by suicide? Yui Hyakuin was resurrected by the "Book," a world-famous entity in Yokohama. The Book tactfully expressed its wish for a world where all three members of the Buraiha were alive. She firmly refused and told it to send her back to her death. ...Then it bought her off. It really wasn't that she gave up too quickly. The Book offered way too much. And so A new library recently opened in Yokohama. A stranger named Sakunosuke Oda arrived at the Armed Detective Agency, asking them to find Ango Sakaguchi, who had wandered off and no one knew where.

Ango Sakaguchi, a lazy, disillusioned slob, sat on a park bench, staring at the Armed Detective Agency's Dazai, who was about to hang himself. Kyoka Izumi and Q Yumeno wore polite, formulaic smiles as they told the Port Mafia boss they weren't interested. Protagonist: I made you a Buraiha. Happy now? The "Book": !!! It accidentally sent them to another worldline. Theme: The victory of NPCs
