Chitose, on the other hand, failed to flirt to her but Keisuke succeeded by accompanying her on eating a gigantic rice ball inside a restaurant at Nakano Broadway.

Keisuke accesses Kamishiro's server but finds out Rie Kishibe is also there. She askes why Yuuko is also there and says: "I am tired and ended up here by accident".

They ask Yu Nogi to pretend Poyomon as his pet, though just before Keisuke could touch Matayoshi, Makiko Date blocks the way and frantically calls Poyomon's cuteness; hugging it so tightly. With the situation they were in, and Erika angrily seeing as if Keisuke is enjoying Makiko's "Bs", she considered to copy the access rights of Date's account instead of the Detective's. Then Matayoshi leaves with Ryuji and Date after answering a call pertaining to a threesome hacker inside Kowloon.
