Ki ga kurui sou na toki ni kuchizusamu uta (気が狂いそうな時に口ずさむ唄)

Kanji

僕はまともだ僕はまともだ僕はまともだ僕はまともだ

Romaji

boku wa matomo da boku wa matomo da boku wa matomo da boku wa matomo da

Translation

I'm honest, I'm honest, I'm honest, I'm honest!

NOTES

-Title translation? "The song you sing to yourself when it looks like you're going mad". That's so awesome.
