Will you stop Sensha-do or will you stop human? A parody of an anti-drug catchphrase in Japan used once at a TV commercial, "Will you stop stimulant, [or] will you stop human?" (覚醒剤やめますか? [それとも] 人間やめますか？).

We'll have a meeting at Sunday 6 a.m.!

I'm quitting Sensha-do!

P-please, wait...

6 a.m. is out of question. No human can wake up at 6 a.m.!

If you have trouble waking up, I'll give some cat's-eye drug tablets, which was used by military! "Cat's-eye" (猫目錠), "battle cry" (吶喊錠) and "assault tablets" (突撃錠) were the other name of meth/philopon, used by the Japanese military.

Philopon Meth

It's written here that it prevents fatigue, boosts recovery and eliminates sleepiness!

Speaking of which, I can give you an ampoule of special medicine made by Clan Nishizumi, that will keep you on your feet for 96 hours...

Clan Nishizumi is awesome!

I'm quitting!
