Aoi: "YOU KNOW THE RULES! FIRST, WE'VE GOT TO STRETCH YOU THOUGH!"

Everyone: "...Yes."

Aoi: "Let's start off with Yūta san!"

You removed his suit, showing the white shirt underneath. You may not have known it, but everyone's face were as red as a cherry.

Shenju: "Are you all sick..?"

Zenitsu: "MARRY MEEEEE"

Aoi: "Shut up piss-head!!"

Zenitsu: "EHH!?"

Aoi: "Whatever! Let's start, Y-Yūta san!"

The girls stretched you with their full strength yet your face was still the same. Your body was so flexible, they couldn't anymore.

Kanao: ".."

Aoi: "Have you stretched a- a lot!?"

Shenju: "Yes."

"Ara ara~ Yūta san... How do you train yourself when you were 6?"

A voice stated out. You turned to the side and saw Shinobu.

Everyone was also quite curious.

Shenju: "When I was 6, I train myself by swimming in a volcano, stretching non-stop for 24 hours, carry houses, 400 trillion push ups, 20 million sit ups, 40 thousand squats, suffocating myself in a pool for 8 hours. Why?"

Shinobu: "Tha- That's got to be a joke... Right..?"

Shenju: "Why would I lie."

Aoi: "WAIT... I DONT EVEN THINK YOU NEED OUR TRAINING ANYMORE!"

Inosuke: "OHH! I'M GONNA DO YOUR TRAINING!"

Shinobu: "Wait... If you trained like this when you were 6, how did you train when you became 14..!?"

Shenju: "some simple training. I run around the whole globe while slaying demons until I can dash around the whole world within 0.2 seconds and I mastered it."

Everyone: "..."

Shinobu: "Better report about this in the next Hashira Meeting..."

Aoi: "Your turn! Yūta san!"

Shenju: "Okay."

Shenju sat on the floor with Kanao.

Aoi: "3... 2... 1-!"

With that, they started. Shenju wasn't fighting back at all, he was just trying his best to lower his speed and match kanao's. Suddenly, she became faster. Shenju decided to use 50% of his speed.

Once everyone blinked, they noticed all the cups had nothing inside.

Aoi: "S-Shenju Yūta wins against Kanao!!"

Trio: "... I give up."

Aoi: "Giving up unless you have severe injuries is forbidden!"

Trio: "EH!?"

Aoi: "Just kidding."

Zenitsu: *sniffle* "That wasn't.. *sniff* funny!"

Inosuke: "OII! YENJI! FIGHT ME!!"

Shenju: "Who's he talking about?"

Kanao: *softly* "I don't know.."

Zenitsu: "K-Kanao! Why is your heart beating so quickly!?"

Kanao turned into a tomato after Zenitsu's statement.
