Tremors

Working at the Sendai City museum wasn't as bad as it seemed on the outside. Tsukishima was able to rest in the dinosaur exhibit, occasionally scoffing at a cluster of spikes in disarray, or teeth that were just-too-sharp. He got to meet all kinds of people, sometimes even twice if he got lucky enough to make a good impression on them. His lack of enthusiasm, and just downright-asshole personality makes it hard for him to weave his way into peoples hearts.
