勝の母親

Masaru's and Shouko's mom.
A lady whose heart is gold and her discipline is strict. Masaru inherited many of her characteristics, while it's claimed that Shouko is more similar to their dad instead.
Even though she's a lot more at home than her husband, she too is working full-time, which is why Shouko often has to cook the family meals and help around the household.
In her younger days she used to be a prominent member of a biker gang, and she only settled down after marrying her husband. Nowadays her main hobby is karaoke, which she often practice 'till wee hours. People call her as the "Karaoke Demon" who's been the ruling champion of the city karaoke contest for ten times consecutively.
