dat ass...!!

"two people bonded together by a butt !"
lol this is hilarious

You have no idea how tempted I am to suggest the Moe up the butt tag

Friendly advice: don't read this in the middle of the class if you don't want people to think you are crazy from sudden burst in laughting.

Page 18 totally made it for me. Not only did the butt help Renko and Mary, it also helped Yukari and Tenshi!

Is it appropriate to add the Butt tag? I really feel like it's appropriate for this.

That was hilarious, I laughed so much, very Gintama style of humor.
