Blue Mango Draws

A headcanon I just came up with on the spot: Shinobu used to give Giyuu a hard time about not eating a varied enough diet (since she only ever saw him ordering one thing, though he does eat more than that), and this evolved into the Butterfly Mansion girls all making extra bentou for him sometimes. He assumes they just had extra, but he has a typical Hashira appetite. They accounted for that much food in the first place. He enjoys them and likes that it's an easy conversation starter, but he prefers to eat the bentou in peace when Shinobu is done chattering.
