Shiro Iwaki has always been gentle, even with the smallest things. His muscles and size intimidate a handful of people, but he truly is the sweetest thing. His kindness and compassion for nature and the world he lives in compel him to put true effort in the plants and flowers he grows. Shiro is very shy, but feels entirely at home within his community garden which he devotes hours a day to. 

Shiro has a low voice, but is not intended to be loud. He speaks very slowly, quietly, and gently. He also has an element of nervousness which constantly lingers, although its appearance differs depending on the occasion. He isn't a stereotypical “soft boy” though, so please try to refrain from that.
