Koriki No. 2

Kojikara is the hamster that Nendou kept in his house. It speaks in Kansai dialect. He had a series of unfortunate disown-ment from a boy to Kusuo→Hairo→Kaidou→Yumehara→Teruhashi→Nendou and Nendou is the only person who finally took him in. He was later shown to have completely been close to Nendou.
