Japanese

(みんなー！　チルノのさんすう教室はじまるよー！)
(あたいみたいな天才目指して、がんばっていってね！)

キラキラ　ダイアモンド　輝く星のように
栄光　志望校　なんとかして入ろう
天才　秀才　トップ目指して　GO GO!!

(バーカバーカ　バーカバーカ　バーカバーカ)
ちょ、ちが、バカじゃないもん！
(バーカバーカ　バーカバーカ　バーカバーカ)
バカっていうほうがバカなのよ！
(バーカバーカ　バーカバーカ　バーカバーカ)
なによ、うるさいわね！このバカ！
(バーカバーカ　バーカバーカ)

紅魔館からバスが出て　始めに三人乗りました
白玉楼で一人降りて　半人だけ乗りました
八雲さんちで二人降りて　結局乗客合計何人だ？

答えは答えはゼロ人ゼロ人
なぜならなぜならそれは
幻想郷にバス無い

山落ち意味など無いわ　キャラクター立てばいいのよ
元気があればなんでも　①・②・⑨！

くるくる時計の針　ぐるぐる頭まわる
だってつぶら目玉　二つしか無いのに
三本の針なんて　ちんぷんかん

次々問題出る　まだまだ授業続く
凍る部屋の中　ひんやりした温度も時間も気にせず
ゆっくりしていってね！

*　(バーカバーカ　バーカバーカ　バーカバーカ)
　　だから、バカじゃないって言ってるでしょ！
　　(バーカバーカ　バーカバーカ　バーカバーカ)
　　いい加減にしないと冷凍するわよ！？
　　(バーカバーカ　バーカバーカ　バーカバーカ)
　　そして、粉々になって散ればいいのよ！
　　(バーカバーカ　バーカバーカ)

※ (バーカバーカ　バーカバーカ　バーカバーカ)
　　バーカバーカ！
　　(バーカバーカ　バーカバーカ　バーカバーカ)
　　バーカバーカ！
　　(バーカバーカ　バーカバーカ　バーカバーカ)
　　もうバカでいいわよ！知らないっ！
　　(バーカバーカ！　バーカバーカ！)

English

(Everybody! Cirno's math class is about to begin!) (To become a genius like me, do your best!) A sparkling diamond, shining like a star Glory, my preferred school, I'll get in somehow Genius, prodigy, aim for the top, GO GO!! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) Wait, no, I'm not an idiot! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) The one saying idiot is the idiot! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) What, how annoying! You idiot! (IDIOT IDIOT IDIOT IDIOT) A bus left the Scarlet Devil Mansion; three people boarded at the start At Hakugyokurou, one left and half a person boarded At Yakumo-san's house, two people left; so how many passengers in total? The answer is, the answer is, zero people, zero people That's because, that's because, There are no buses in Gensokyo! There's not any climax, point, or meaning. Everything will be OK as long as the character settings are fine 'n good With energy, everything is 1, 2, ⑨! The clock's hands are whirling, my head is spinning round Because there are only two round eyeballs, There are three needles, it's as clear as mud Problem after problem comes out; Still, still, the lesson continues In the frozen-aired room, without considering the temperature or time Take it easy! * (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) 　　I told you I'm not an idiot, didn't I? (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) Give it a rest or I'll freeze you! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) Then you can shatter into little pieces! (IDIOT IDIOT IDIOT IDIOT) ※ (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) 　　IDIOT IDIOT! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) IDIOT IDIOT! (IDIOT IDIOT IDIOT IDIOT IDIOT IDIOT) Fine, call me an idiot! I don't care anymore! (IDIOT IDIOT! IDIOT IDIOT!)
