As always, only take this translation as something to reference and trust the official eng version when it releases!
I don't scan any of these raws and mainly translate them through a translator!

Mafuyu:
"Big brother, how do you even use this!?"
Natsuki:
"It's impact!"
Just give the shoe an impact, anything will do!"
"The shoe converts that impact into energy, and the jets will activate!"
Mafuyu: "Huh!? That makes no sense..."

Kippei:
"Whoa, it's already dark out"

"Ouch"
"Whoa!"

Shiina:
"Big brother!"
"Even big brother couldn't react to that...!"

"Idiot"

Shiina:
"Ah!! This guy again...!!"
"My weapon...!"

Shiina:
"Damn it... you coward...!! You're pretending to use that weapon for the first time...!"
Mafuyu:
"No, it really is my first time using it."
Mafuyu (Flashback):
"How many times do you think I've been used as a guinea pig since I was a kid?"
Natsuki:
"Next, Mafuyu."
Mafuyu:
"I know my brother's weapon habits better than anyone."
Shiina (present):
"That's cheating! Fight fair and square, one-on-one...!"
"Big brother! Are you okay!?"
(page 8)
Natsuki:
"Right here...!"
(page 9)
Shiina:
"Wait...! Big brother, what are you doing just standing there!?"
"So fast! This is bad..."
"I won't make it in time...!"

Wha...!"
