#kazui

Absolutely ... especially when Kazui was a baby.

First and foremost: Aizen must solve the mystery of Kazui's crying and how to stop it. Because if it continues on like this, he might slip back into his old ways of kill first, talk later.

He will try every tactic with patience. He will take a mental note of what works and what doesn't, hoping that with time, he'll reduce 'making kids shut the hell up' to a science.

Spoiler alert: the experiment fails. Kazui: 1. Aizen: 0.

His next foe is soft tofu. Kazui likes picking up the cubes and squeezing them in his little palms, but he detests eating it. On the other hand, he seems to like the taste of sweet potato, but the texture gives him a fright. Orihime insists that Kazui must eat both ... but to what end?! Aizen tries blending the two together - fail. He tries hiding small pieces of tofu amidst larger chunks of boiled sweet potato - fail. He's determined to get this right, though. This child will not outthink him.

The winning recipe: okayu with sweet potato blended into it, topped with tofu cubes.

Aizen also wants to understand the depths of a relationship that a child has with their favorite stuffed animal. He sits Kazui down and begins a puppet show of sorts. First, the stuffed bunny (a gift from Auntie Rukia!) has a dance party. Kazui really liked that. Then, the bunny is told that he has a terminal illness - and starts to cry. Kazui doesn't understand that scene, tiny brows pinched in confusion, so Aizen skips past it quickly. The grand finale is the stuffed bunny being hit by a toy car.

Kazui really doesn't like that one. Aizen tries to apply everything he learned from experiment #1 ... but again, it was a failure, so he must suffer with a wailing Ichihime-clone for the remainder of his stay.
