Guess Ryuuko ain't the only one that gained weight. Then again when you're not fighting evil sentient clothing for the survival of the human race you're probably not going to do a whole lot of exercising.
You're gaining weight.Why that face? What's with that face!!?Mako! You've gotta help me out here!Don't you know about that phase!? The growth spurt!Hm, you really are growing.Ryuko.What! What're you talking about, Sis!I'll just subtract my weight from the results, then.If you don't believe me, go weigh yourself.WAAAAAARGH!!!!Sideways, that is!Good luck~!*Squiiiish*Stay still! You're heavy!No matter what, I won't lose to you, Kiryuin Satsuki!!!Stop horsing around, Matoi Ryuko!!!No wayyyyyyy
