OBD-075 Miss Deriheru is Grandma Miyuki Tsubasa

Tsubasa lives with his son and his grandson for three generations. He has a humorous personality and often surprises his surroundings. Recently, I often go out with make-up, but my family doesn't care. However, Tsubasa has a secret part-time job ... One day, Kazuki, a grandson who was alone at home. Kazuki calls Deriher just here and there. The intercom rang, and the one who was in front of me when I opened the door with excitement was ... Grandma Tsubasa!
