部内戦開始 / Scrimmage Showdown
あはは♪
てい、てい、てい、てい、て～～～い♪
Ahaha! ♪ Hup, jump, hop, leeeaaap! ♪
The English one had a good idea to make the tei tei tei tei tei~ work.
わわわっ！？
ご、ごめん、ごめんってぶちょー！
Uwahhh?! Okay, okay, I'm sorry, Captain!
演技に軸を持つんだ。
自分の中にある軸を。
You need to construct your performance around a solid foundation that reflects your character.
ひぃ。
Hrrrmmm...
“Solid foundation” is just a tiny “jiku” 軸 kanji in Japanese, meaning the core / the axis (inside oneself). (e.g. When you go buy mechanical keyboards in Japan, the choice of microswitches would be selecting which color of “jiku” you want. Yes, this is one of the not very useful things that somehow stuck with me after doing a master’s degree for 2 years in Japan…) But this exact kanji is important to the story.
あはは。キャノさんの演技、ちょっと自由すぎるところがあるけど……
カケルくんはどう思った？
Ahaha. There are aspects of Cannie's performance that may be a bit too free-spirited. But what did you think, Kakeru?
ハッピーな気持ちになりました！
スキップしながら鼻歌を歌いたくなる、みたいな！
Watching her gave me this feeling of joy! Kind of like...I just wanna skip along while humming a tune!
This is likely a reference to “Laugh to Laugh to Love” that you have just played and unlocked, which features the rail skip-jumping to fit Canon’s performance style. (And you also have to do triplet swings by ear while it is doing that in the Master chart.)
はい！
うっし、やるぜ～。
Okay! I can do this!
“Usshi” for “here I go” came back again.
レッツ、グルーヴコースター！
Time to groove!
Again, I wish they used LET’S, GROOVE COASTER! literally. (With the comma.)
Like Canon, Kakeru isn’t yet “awakened” at this story point, so Kakeru uses a generic “Let’s” like Canon’s “Go! Go!” earlier. If the English one used “Let’s GROOVE COASTER”, maybe English players would realize sooner that “Let’s” could be upgraded later, as might have been hinted at by Aria’s “Kanaderu (resound), GROOVE COASTER”.
