Masaru nodded as Kotarou explained his choice.
"That makes sense. You knew what you had, and had some idea of what I had, going in.
I'd say you want to try working on active defense methods in all your forms. Your "passive" defense, the protection the armor gives, can't really be changed with just training. I mean, all our swords grow more powerful as time goes on and with training. But you can always improve how you move around in a fight. Not that I'm perfect at that!"
He gave a laugh, then shrugged self-consciously at the praise.
"I guess. The big lizard's part of me. We both like fighting, and since he's a sword, it'd figure he'd want me to be good with one."
He seemed thoughtful at the advice.
"I'll have to play around with it. That said, I get the feeling it's not a "regular" portal, so at most risk it'd have to be someone else with shadow-related powers. Not a lot of those running around, last I heard."
He grinned then.
"Before you know it I'll have Bankai or something, Koutarou. We'll both keep striving to surpass each other, and ourselves!"
He slammed his fist into Koutarou's (though nowhere near full force).
"Brothers in arms!"
SpoilerOOC: I can't believe I forgot this for like 2 weeks.
