Ehhh? So Usahara is from Kyoto? I wonder if he's from one of those rich ancestral families who decided to strike it big in Tokyo but really didn't make it far. (or he could be from one of those farming families too in Ohara, I could certainly imagine Usahara in farming gear)
One day, I pray that thicc-ass breastplate would disappear. It's only a matter of time before Jade's back would give from the ridiculous shape and probable weight.

The gifts to family are most likely obligation-type gifts (given out of gratitude) but to your special person...
