Decchan

Decchan (でっちゃん, Decchan) is one of the protagonists as well as the incarnation of Dead Master in Black Rock-chan.

Description
Decchan largely resembles her original counterpart, with the lack of wings on her back being the main exception. She is a motherly figure to the child-like Rock-chan and cares for her deeply, although she also shows a scary side occasionally.

She also works part-time at the weapon store to pay a debt after Rock-chan's Rock Cannon, which was awaiting repair, ended up destroying the store while the owner was away.
