Goujin has a hard-working and nice personality, but seems to be lacking emotional strength and some knowledge about certain things. For example, he didn't know who Endou Mamoru was, shocking all of his teammates and he thought Fire Tornado was Fire Lemonade while training for a hissatsu with Hiyori. He easily gets angry when he doesn't agree with others comments.
