Ai Shimizu) :Sakura Tamaki is a mysterious girl Hatsuyuki meets in the ruined old town, while she is searching for her bunny Nemu. She is somewhat weird and likes to use Nemu for BUNNY impersonations, which include things like the simple bunny, bunny-copter, old man’s beard, muffler, etc. She is strangely attracted to Hatsuyuki and has the habit of holding his hands whenever they are together, saying that his hands feel good. Highly allergic to adult themes in conversation, she is prone to scream "pyaa pyaa" and escape the scene whenever she hears it. She attends the same class as Hatsuyuki and seems to be a normal genki girl who gets along with everyone. ; :Voiced by:
