This was probably the first time the characters name-dropped Onsen Mark. I was kinda hoping they wouldn't. Viz's literal translation "Hot Springs Emblem" doesn't exactly roll off the tongue. Ugh.
I think all the stories Onsen Mark told were covered in the manga at one point or another.
Holy crap. Takahashi actually showed minors drinking. This probably isn't the first time but I think it's the first time Ataru and the others went out of their way to get a drink. That surely wouldn't fly in today's anime.
I like that the old guy was still able to get revenge somehow lol.
