麻衣「ごめーん、おくれちゃった」
ゆっこ「麻衣ちゃん、おそーい(苦笑)」
みお「……」
麻衣「補習抜け出そうとしたら、先生に見つかっちゃって…」まいった
ゆっこ「赤点取ったの麻衣ちゃんでしょ、かりそめにも」
麻衣「ほら、なにしろあの時は若かったから…」
ゆっこ「若いって何分前の話よ！」
麻衣「そうだった」ぺろ
　
みお「あれ…」
　
なの「…おい、麻衣っぺ！ったく、いつもいつもおっせぇんだよ、おめーはよぅ」
麻衣「なのっち、ごめーん☆……あー、ほっぺの傷！またケンカしたでしょ」
なの「っせーな、ほっとけっつってんだろ」
麻衣「ダメだよぉ、なのっち戦闘ロボなんだから、相手潰れちゃうよ？」

日常（六）P35『日常の92』、通称『輪入道』より。
アニメ化を切望されながら結局放送されず、世のギャップ萌えストが失意のズンドコに叩き込まれたのは記憶に新しいところ。
頭の切れるゆっこと元気な劣等生の麻衣ちゃん、見たかったなあ。
　
原作では三人衆だけだったエピソード(トランプタワーや漫画の手伝い)になのちゃんがいたんだから、もし放送されていたら、きっとなのちゃんも居たに違いないなと。
みんなの性格がどこかおかしい、ちゃんみおの夢の中。その中でのなのちゃんは、果たしてどういう性格に……
　
……って、まあ、一択という気もします。
　
　
余談ながら、なのちゃんが咥えているタバコは……「KOOL NANO 8mg」。ｗ

Mai is smiling, clinging and saying something not-Mai-ish...either she is trolling hard or I'm dreaming.

This Mai-chan is okay, too.

Spy! That Mai is a spy, I say!

Maybe Mai just has a thing for delinquents..?

Not much of a person for translations, but here is my best shot:

Mai: "So~rry, I was late..."
Yukko: "Mai-chan, you're so slow! *bitter laugh*"
Mio: "..."
Mai: "I tried to get out of remedial lessons, but the teacher found me." *Mai'd*
Yukko: "Just be the failure-toting Mai-chan, for the moment."
Mai: "You know, I tried to blame it on being young anyway."
Yukko: "That's what I was just saying a minute ago!"
Mai: "I see." *lick*

Mio: "What."

Nano: "Oy, Maippe! Geez, yer always, ALWAYS so late all deh time."
Mai: "So~rry, Nanocchi☆... Ahh, a scratch on your cheek! Another fight?"
Nano: "Yeah, he wouldn't leave me 'lone."
Mai: "You mustn't do this, because you're a combat robot, Nanocchi, and you can just crush your training partner, right?"
Nano: "Of course I won't, wut wit' a wild geezer like dat fer a trainin' partner, gotcha?"
Mio: "Wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha-wha????"

Following Nichijou #92 (AKA, "Wanyūdō"), volume 6, page 35.
While I was initially eager to see it in the anime adaptation, that world's gap-moé* strike was a frustrated Zundoko that struck while it was still fresh in memory.[translator's note: this entire sentence was nigh-incomprehensible to me; check the translation, please.]
A brainiac Yukko and an energetic duncehead Mai-chan, I really wanted to see that.

Because this was originally a trio-only episode (Trump Tower or manga assistance) before Nano-chan joined up, then surely Nano-chan would have been different as well.
Something was off about everyone, in Chan-Mio's dream. About the Nano-chan of that dream, her personality would surely be...

...er, well, this is just one feeling about it.

As a brief aside, that cigarette that Nano-chan is munching on is a... "KOOL NANO 8mg". lol

*[translator's note: according to my research, gap-moé is a Japanese term that references how one's image of a person differs from the reality of that person, but you find the difference (the gap) to be moé.]
