Mrs Ikaruga

Mrs Ikaruga is the wife of Hoji Ikaruga.

10 years ago, she wore a kimono and had short hair parted in middle. Later when Sayo Ikaruga was older, she appeared to wear a black shirt and her short hair is with bangs. (It's unknown whether the two appearances are the same person, though)

Plot
In a flashback of Shimon Ikaruga, she appeared as watching TV with Hoji Ikaruga, and asking Shimon to see whether Sayo Ikaruga has fainted at bathroom.

In another flashback of earlier time, she asked Shimon that if he was alright, for Shimon didn't have the appetite, thinking about Tenma Unomiya.
