Shiko's House

Shiko's House is the home of Hiroshi Kotetsu. Technically, Shiko and possibly Shin Kotetsu live there as well but choose to live in tents out of personal preference.

Features
Similar to the homes of Seto and Reito, it is based on a lab from a mecha series. In this case it is based on Build Base from Steel Jeeg. As Shiko never enters her house and lives by the riverside in a tent, the interior is never seen in the series. Given Hiroshi's occupation as an archaeologist it may contain artifacts as well as a laboratory for maintenance on Shiko and Shin.
