GINTAMA X RWBY CROSSOVER

Gintama -Remnant arc -ch21: learn to play an instrument instead being a showoff.

During the fight with two members team CRDL again Penny and Ciel, this whole time, Gengai, when he came to Remnant, was dismantling and rearranging any mechanical and robotic stuff he can find. He stayed in a special room for himself. Oobleck just so happens to pass by and notice the old man working.

Oobleck: "you must be the infamous Gengai, I presume?"

Gengai: "you must be one of those tutors in this academy. What can I help you?"

Oobleck: "actually, I thought to myself that you may need someone to talk with since you seem to be alone all this time."

Gengai: "no worries, I'm used to it. I'm just seeing what make this technology different from our world (especially from the amantos)."

Oobleck: "maybe someday, you can show us about your world's history and advanced technologies."

Gengai: "well, prepare to have a lot of disappointment."

Oobleck: "I beg your pardon?"

Gengai: "hum... With those parts, I can make robots just like mine."

Gengai continue his research, letting a confuse Oobleck next to him.

Meanwhile, at the Colosseum...

The fight against the two teams ended a while ago (due to Penny having a crushing defeat). Ruby just got back from talking with her robotic BFF and sits next to Blake and the odd jobs.

Ruby: "this is gonna be exciting. With Yang and Weiss, they're definitely gonna win."

Kagura: "I do hope so. Nobody is a better brawler in this school than Yang aneko."

As Ruby sits in her place, she felt something... Bumping. She gives a look under her sits and discovers Madao was under, eating a box of popcorn. She raises her head with an absolute confuse expression on her face.

Ruby: "hum... Blake? "

She calls her friend for assistance. As the Faunus cat turns her head to the little red hood, Ruby points down where's the problem. She was shocked to see Madao under Ruby's chair... Eating popcorn.

Blake: "okay, what ?"

Gintoki, noticing the problem, answer them...

Gintoki: "oh, I forgot to tell you, my bad. I helped him getting here so that he can watch the match."

Madao: "sorry girls."

Ruby: "but why he's under the chair ?"

Shinpachi: "for two reasons. One, is to hide from the robot that is guarding this place. And two...

Kagura: "because he's a madao. A cockroach from texas."

Blake: "what's texas ?"

The two girls didn't know what to say. Instead the cheering spectators and Madao drinking a soda, there was a awkward silence. But they put this aside because now, the two duo teams just enter the arena.

At the same time, with fire and ice...(i mean Yang and Weiss)

Yang: "welp, now it's our turn."

Weiss: "just remember to keep proper form."

Yang sighs and ask : "alright. You're from Atlas, what can we except ?"

Weiss: "well, seeing as their kingdom, academy, and army forces are all merged as one, I think we can except strict, militant fighters with advanced technology and carefully rehearsed strategies."

Suddenly, something from distance dash behind them and just happens to be one of their opponent in front of them. One is a Faunus girl with a tail, roller shoes and all dress up like some cheerleader, and the other one is dress like some musician who plays some blue jazz with a trumpet. Nobody, not even the Odd job nor Yang and Weiss were expecting that.
