(the episode starts with Shu and Bouquet riding on a train as it shows a seaside village)
Villager 1: that's ridiculous. It only takes one Yokozuna to end a duel nowadays,so a sensei taking residence in the mountain is just silly
Villager 2: I'm not lying,a young villager who went to the mountain said he saw it a few times
Villager 2: he must've seen something else,maybe an animal or something?
Villager 2: but look happen to Noi,he went to get some firewood and come face to face with the Rikishi,he's been bedridden with injuries even since,so I doubt he just made it up
(at a forest,Noi is picking up a mushroom)
Noi: I found one,and big one too
Andropov: let's head back Noi…
Noi: What are you talking about? We need to find more,let's go in a little deeper
Andropov: I don't want to! I heard that there's a Yokozuna deep in the woods,so I don't want to be hurt!
Noi: like that ever happen
(Andropov sees a crow and runs off)
Noi: coward! (walks away) no way…a Yokozuna is here? (he searched deeper and sees Shu and Bouquet training)
(at the sunset)
Shu: (licking Bouquet's finger)
Bouquet: (giggles)
(that night,Bouquet is practicing metalbending)
Bouquet; come on metal,budge,(punches a metallic block hard) whoa,Bouquet,you rule!
(the next morning,Noi is spying on them)
Noi: sugoi,guess they're sumo fighters,here to stop the invading Rikishis
(Shu noticed something as he run out the door and sees Noi)
Shu: oh it's just some villager,what are you doing out here?
Noi: …
Bouquet: this place is off limits,now leave
Noi: Sensei! Sensei! Make me your apprentice!
Shu and Bouquet: …
Noi: there's someone I needed to defeat! Please,make me be your apprentice Sensei!
(inside the dojo)
Noi: my mom's a peddler,she pedals rice and fish and sell them in town,every morning she leaves the house early and come back in the afternoon to get paid by a guy known as Yasushi Oegawa at the station for hawking his goods,it happened the other day,I was waiting for my mom to come from work at the station
(flashback started)
Noi: oh here it comes
(at the train station he comes looking for his mom as he saws one of the women being held sex slaves by Yasushi Oegawa)
Noi: ?!
(sees his mom licking Yasushi's belly)
Noi: so there you have it,that's why I need your help to save her
Shu: very well
Bouquet: you can count on us
Noi: …
(later that day,Shu and Bouquet is training Noi)
Noi: …
(elsewhere)
Yasushi Oegawa: …
Noi's mom: welcome home goshujinsama,from now on,I'll be loyal to you
Yasushi Oegawa: (shows Noi's mom his foot)
Noi's mom: wagata (starts licking his foot) goshujinsama,your foot tastes so good
(suddenly Shu,Bouquet and Noi barges in)
Yasushi Oegawa: who are you?
Shu: were the sumo fighters and where to take you out
Yasushi Oegawa: bring it! (performs a shiko)
Noi: (performs a shiko as well)
Karate girl: hakkeyoi,nokotta!
(another karate girl kicks a taiko with her bare foot)
Noi and Yasushi: (battle cry)
(duel scene)
Noi: (throws Yashui out of the ring)
Yasushi Oegawa: (disappeared)
Noi: okasan! Are you ok?
Noi's mom (nods her head as she hugs him)
Shu: well that's over with
Bouquet: yep
The end
