About
Iruma and the others have accidentally drunk "Relax Ju~ce" undiluted, even though it's supposed to be mixed with water!! It contains absolutely no alcohol, but it's a substance that makes your energy skyrocket when you drink it. Having it straight means their energy is going to explode...!? (They are acting as if they are drunk on alcohol.)
