yup those to(Nagato and Musashi) Become a Muscle Idiot after getting Kai 2.
How come Mutsu not become a Muscle idiot in her Kai 2 after getting it and keep it's maturity?
with muscles...?Utterly inconceivable... there are things... that cannot be solved...Ach so! You have no inkling of what a relationship between a man and a woman is!You "My lover is the bench press"-like people should just keep out of it!At times like this, you should do some muscle training together to clear the air, and...Even I can be in love...Even I...Let's just calm down, shall we?There are some things that you can't solve with muscles!Indeed!
Those who are enamored of the same man shouldn't be having a war of words like this, no!Now, now, you two.
