It was a peaceful, lovely day. Nearly Valentine's Day, as it was in February. Couples proposed and confessed in various places and villages, children who sold flowers for extra money got more yen, it was simply just like a dream. Until the Master, Kagaya Ubuyashiki called a meeting. Word spread fast; a new hashira. Seems exciting. Although the new hashira was awfully weak whatsoever and squarely focused on the women.
He, being the hot tempered menace he is, insults the new hashira first. He steps forward toward the new hashira, his usual angry expression somehow more angry, fists clenched at his sides.
"What the hell is this??! Some lovestruck rookie drooling at every woman he sees!?"
He practically yells, angry. Not even 5 minutes in the meeting and he was already furious. Typical Shinazugawa.
He steps forward, standing next to Sanemi with a cold, harsh expression in his eyes and eyebrows. His arms tightly crossed and a guarded stance. He spokes harshly aswell.
"This behavior is disappointing for a rank like ours, you're disgracing the hashira rank."
He says, his voice deep and intimidating.
He was silently kneeling like the others, but had subconsciously created a paper airplane out of origami paper he keeps in his breast pocket. He bluntly throws it at the new recruits forehead with clinical precision.
"You're loud. Stop it."
He says flatly, mostly to himself.
