Orie Takarada

Rikka Mama (六花ママ) is Rikka Takarada's mother. She is the owner of the Junk Shop.

SSSS.GRIDMAN
She and her daughter found Yuta Hibiki passed out in front of the Junk Shop and brought him inside to rest. Ever since then, she and her shop were frequently visited by the likes of the Gridman Alliance members and the Neon Genesis Junior High Students, since the old computer where Gridman resides, Junk, is located in her store.

Just like almost everyone else, she forgets about Gridman and the Kaiju attacks the day after they happen.

Trivia

 * Like most of the cast, Rikka Mama's color scheme and design are inspired by a character from the Transformers franchise. She has a pattern on her apron that matches the pattern on the abdomen of the original incarnation of Megatron.
