Koi wa Sekai Seifuku no Ato de

There are two sides to every coin...light vs. dark, good vs. evil, love vs. hate. Sometimes the line between the two grows thin...and it's so, so easy to cross. So it's no surprise that Fudo Aikawa, A.K.A. Red Gelato of the Gelato Five and hero to all people, just may have happened to fall for the villainess and member of the shadow organization Gekko, Desumi Magahara! But when opposites like these attract, there's more than a few obstacles to their love...! What's a pair like this to do?
