Kakeru is a legal prodigy who started at a very young age. With his experience as the Ultimate Lawyer, he is a proficient speaker in court. However, in contrast to this confident side of him, he is actually a timid and shy person, struggling to initiate a conversation with other people in his daily life because of his intimidating appearance. He is of considerable height and musculature, more so looking like a muscled gang goon than a lawyer, but he tries his best not to intimidate others.
