Gonta likes animals very much, especially insects, and he can even speak with them. He is a kind-hearted, gentle, and polite person. He is very pure and naive, as he easily believes strangers and can get easily discouraged by other people's comments. He himself acknowledges and often points out that he is dumb, which is one of the reasons why he listens to other people so much. However, despite his gentle nature, he can turn very angry if he sees or hears someone hating on insects, and he believes bug lovers can't be bad.

In order to repay his woodland family, he aims to become a true gentleman. He wants to be useful to others, but he prefers not to do physical fighting and violence. He also gets very ashamed of himself if he does something a gentleman wouldn't do, like telling lies, losing his temper, making rude assumptions, seeing someone naked or half-naked, or accidentally touching someone inappropriately. It's noted that he isn't very gentlemanly yet, as he's a bit clumsy and sometimes gets controlled by sudden and strong emotions, but he tries very hard. He sometimes fears he might never become a gentleman.

Because he spent his childhood in the forest, he is lacking general cultural knowledge, and so he often has trouble speaking with the other students. This is made worse by his intimidating appearance. Because of his appearance, he doesn't like to start conversations, and as a result, when someone approaches him, he would like to say "thank you" as in "thank you for talking to me.
