He is the leader of the Shinjuku Academy Scouts and know everything there is to know about hiking. He does part time jobs around Shinjuku and Ikebukuro while pitting himself against the moutains of other worlds that have appeared in Tokyo. Whenever he's not working, he's up in the mountains, resulting in dangerously slow attendance rate at school. The third eye on his forehead gives him a sixth sense that shows him the right path to survival even on the most treacherous of mountains. He is extremely strict on anyone who underestimates or desecrates mountains.
Translated from Japanese
A summon and the reliable Shinjuku Academy Hiking Club president who knows everything there is to know about mountain climbing. A mountaineer who challenges the mountains that have appeared from other worlds while working hard at part time jobs from Shinjuku to Ikebukuro. Outside of work he tends to seclude himself on the mountains, so his attendance record is in serious jeopardy. The eye in his forehead connects to the sixth sense, and its gaze can show the correct path to take for survival no matter how harsh the mountain. He is highly severe with those who disdain and pollute mountains.
His Hiking Staff Sacred Artifact holds the Rule of Traverse, wich overpowers that which he treads upon, but due to that Rule, no matter how treacherous a moutain is, once he completes it, it turns into an easy hike for him. He wants to constantly challenge himself to conquer new and unknown moutains and answered the call to come to Tokyo to seek out the moutains of other worlds. All of his knowledge is focused on hiking and his private life is centered around living on the moutains. Thus, he is ignorant in practically everything else. He loves mountains so much he's been known to take it to extremes.
Translated from Japanese
He carries a walking staff Sacred Artifact with the power of "on foot travel," the ability to overcome anything he treads upon. But because of that power, no matter how rugged a mountain may be, once he steps foot on it the mountain ends up becoming an easy one to him. He constantly wants to try climbing unknown mountains, so he always seeks still unseen difficult mountains from other worlds and responded to the summon to Tokyo. Given that all his accumulated knowledge relates to mountain climbing and that in private it's fundamentally about living in the mountains, any knowledge he has outside that field is unusually disconnected from the earthly world. He likes mountains so much that sometimes his eccentricities become visible.
Due to the influence of another person, the mountain scenery he had always seen has changed. For him, this awareness was an extremely novel and vivid event. Now he wants to see even more different kinds of mountains, and this feeling completely overwhelmed his heart. So upon the suggestion from a dwarf at one of his part time jobs, he jumped up with two answers. He was so excited about the day everyone would go mountain climbing that he couldn't sleep. After all, mountains were the best thing anytime anywhere. The Sacred Artifact tied by fate to his homeworld was once again summoned to this Tokyo, carrying an unfortunate relationship to that summoner.
