Mashirao has a very calm and noble attitude, as well as a very deep sense of dignity, which prevents him from accepting results that he doesn't feel like he earned with his own abilities. He is also described as a hard worker. Along with a strong sense of dignity, Mashirao can be described as sheepish and bashful, not very often enjoying the spotlight and being easily embarrassed. He is quite humble, yet also reliable and focused during hero work. A recurring joke is that others tend to view him as "plain", something that deeply upsets him, showing that he's sensitive and self-conscious about his own personality and abilities. He tends to be shocked quite easily. When something excites him, he wags his tail, in a similar fashion to a dog, though this is only ever seen in the manga.

If you could sound similar to his English VA, Mike McFarland, that would be great, but it is not required!
