This is a parody on the scene where Misumi/Shiva's sitting alone and he unscrews the end cap on the hilt of his sword (ep. 86).
Yours...... Part I
Misumi unscrews the end cap... and brings out a tea cup out of nowhere. Tilting the ''sword'' he pours himself a cupful.
Text pointing to the drink: Coffee.
Text pointing to the cup with a picture of a very young and cute looking Wakasa: My petit cup.
Blowing at the hot coffee, he leans back against the wall.
Misumi: {.......He's late---... How much longer is he going to make me wait? I even have enough time for a sip--...}
Large text: ...A huge thermos....
Small text (Nakamura's personal comment): ...It's just that... The trick hilt on the Japanese sword made me think of this...... ...and I've brewed some at my workplace......
