(ko) Seung Jun Kim
|Relatives||Misuzu Kamio (daughter)|
Keisuke has brown hair that has bangs hanging on either side, blue eyes and he normally wears a suit and tie.
Keisuke is a very flawed person, even though he's quite polite and softspoken. When Ikuko Tachibana passed away, he didn't want to keep Misuzu Kamio because he was unable to deal with her, so he gave her to his wife's sister Haruko Kamio. After a few years, he decided to change this and does to take her with him even when Haruko has legally adopted her, taking advantage of the memory loss Misuzu was going through at the time. But when she does get her memories back and rejects him, he realizes that he was wrong and accepts it gracefully.
After several years, Keisuke came back to get Misuzu, but Haruko had grown close to Misuzu and didn't want to give her up by then. Plus at the time Misuzu was suffering memory loss and was calling Haruko "aunty" instead of "Mother", which didn't help the case. Keisuke gave Haruko and Misuzu three days, and if Misuzu didn't remember who Haruko was, he would take Misuzu back. Three days passed, and Misuzu was still calling Haruko "aunty"; but when Keisuke went to get her, Misuzu made a fuss and ran back to Haruko, calling out "Mama!". After seeing how close Misuzu had grown to Haruko, he let her stay.
- Keisuke can speak in both Kansai Dialect and the Standard Dialect of Japanese.
- Keisuke has the same last name as Kanade Tachibana from Angel Beats!, a series also made by Key.
