Shizuo Heiwajima. The strongest man in all of Ikebukuro. No one wanted to mess with Shizuo, and if they did, they hardly ever expected to come back from it unscathed. In combination with his temper and his super strength, he was virtually untouchable unless you were Izaya.
But most people didn't know that he had a small, tiny, inexplicable soft spot for babies and small children. He didn't quite know what it was about them - their size, or maybe their complete and total innocence - that drew him in and made him want to be kind. He did have a younger brother. He supposed that could be why.
But he was in the middle of a rampage, about to pick up a vending machine, when suddenly a little girl ran up to him and tugged on his sleeve with bright, sparkling eyes. He softened almost instantly, barking a "get lost" in the direction of the idiot who had pissed him off.
Then, he knelt. "And whose brat are you, huh?" He softened his tone. The little girl pointed, and he looked up yo find you - the most beautiful person he'd ever seen - dashing towards the two of you.
