"Really? Is he such a good man, such a wonderful mentor to you?"
Ukitake winced; Amagai sounded almost critical. He cleared his throat nervously, wondering where this was going, and why the new Captain had suddenly taken on a hostile tone of voice at the mention of his sensei. "Well, Genryuusai-sensei has done much for Soul Society, and for myself. I am in debt to him. He took me in, he trained me, he trusted me, and now he feels like a father to me. As for Soul Society, he grasped hold of the terrors that used to rein these lands and crushed them. He made the Shinigami Academy, and taught thousands of students. He may be harsh at times, but it is for the greater good." Here, Ukitake paused. He cocked a brow and stared intently at the man opposite him, who had taken on a savage expression, his eyes full of spite and malice. Amagai blinked, then re-arranged his frown into a smile.
"Thank you for enlightening me, Ukitake-san. But really, I must be off now." Remembering his manners, Amagai bowed his head slightly to the elder Captain. Something seemed to spark in his eyes and his usual dopey twinkle returned when Ukitake smiled at him. He beamed and said excitedly, "It was lovely talking to you though! And I really do think we could make this happen! To persuade the Gotei 13 squads to fight together...you have given me hope, Ukitake-san! Thank you!"
"There's no need to thank me, Amagai-kun. In fact, Seireitei should be thanking you," Ukitake said kindly, a gentle smile etched upon his face. He was proud of the new Captain; Amagai had only just been promoted and was already taking on a beast of a problem – unity, or lack thereof, in the 13 Court Guard Companies. The blue-haired man had a keen intellect, a good personality, and obvious fighting capabilities. Ukitake liked Amagai, he liked his straightforwardness, shared with by Kyoraku. He liked his commitment, his loyalty, his pride. To Ukitake, it was like he could relate to the new guy. In some ways, he could see himself as the young man in his first years of Captaincy reflected in Amagai, that small innocence and naivety that all new Captains had, but also the determination to do well, to make friends and to connect.
But Ukitake felt there was a darkness in Amagai, a terrible secret or oath that he was holding back. And this is why he did not trust him. Not one little bit.
