I can't be the only one who thought he was talking about smoking weed when he asked if they wanted to be "lit up". It's Karma Tatsurou, I wouldn't put it past him.
Lit up along with the deceased, huh...

An old tradition to...heat up oneself through sex? That's great and all, but all the...awkward meetings with others hoping to participate in said tradition are just really...well, they must be pretty damn awkward.
