Minato became president of Kibou Company after his father left, despite initial uncertainty and previous unemployment where he criticized predatory employment practices. Expelled from Imperial Company for workplace violence, his internal Imperial assessment noted seven-star command and analysis skills, contrasting his official two-star adventurer rank. He has long brown hair tied in a ponytail with a yellow ribbon, green eyes, and typically wears a red jacket over a white t-shirt, off-white pants, a blue tie, and brown shoes.

Childhood friend and company secretary Yutoria convinced him to accept the presidency. On his first day, he discovered Kibou faced bankruptcy. To save it, he sought his inheritance, requiring substantial tax payment. He entered Kibou in a young adventurers' contest to raise funds, competing against rivals Cyedge, led by Rivar, and Imperial, represented by Subaru. During the contest, Minato tactically coordinated with Cyedge to defeat a three-headed maju monster, though Imperial claimed the prize.

Later, Minato joined a treasure hunt proposed by Marika, a self-proclaimed genius wizard. They explored her grandfather's haunted mansion, an experience teaching Marika friendship's value, leading her to share bracelet sale profits with Kibou. Retrieving a form at Marika's residence transported them underground, where powerful majus guarded rare earth minerals. They escaped, using intelligence from Rivar's injuries to prepare for a subsequent mission. There, Minato's team defeated the maju boss by healing its subordinates, showcasing unconventional problem-solving. The rare earth proceeds paid the inheritance tax, averting bankruptcy. Minato then found his father's message revealing the tax was a test of his leadership worthiness and that his father journeyed beyond the Big Gate.

Throughout, Minato displayed kindness, gentleness, and a soft-spoken nature, balanced by analytical command in combat. He expanded Kibou by recruiting Marika and Mineko, a speaking maju outcast. His leadership fostered teamwork and morale, evident as the company stabilized and employees pursued independent adventures. His journey shows a transition from reluctance to dedicated leadership, driven by protecting his team and honoring his father's legacy.
