If Yuru Yuri managed to refresh its franchise by introducing an Ōmuro-ke spin-off, why can't Wataten do the same with a Matsumoto-ke spin-off?
Although Matsumoto is literally a copy and paste of Chinatsu's sister when she sees Akari's sister.

Because Matsumoto is a one dimensional side character whose only attachment is the worst main character. Brat is a glorified main character, and more interesting the the actual main cast.
