Yasuhiro Hagakure is a character in Danganronpa: Trigger Happy Havoc, and his title is the Ultimate Fortune Teller/Clarvoiyent. Yasuhiro is one of the more cheery, laid-back students, though a bit odd as well. However, he is generally not well-liked and he himself has openly admitted that he has no friends, is quite cowardly, lazy, slow-witted, and has a habit of acting selfishly. Notably, he is mentioned to be very clumsy with money and he has constant problems with massive debts. This trait is especially apparent when he stated that he bought his crystal ball (which is made of glass instead of crystal) at the price of 100 million yen due to it being used by famous figures in the past. He has also bought multiple items related to fortune-telling, despite not actually having any use for them. He tends to talk absurdly about subjects such as conspiracy theories and the one-time aliens stole his hamburger. However, he hates it if someone compares his fortune-telling to the occult, frequently insisting that they are not the same. He is also afraid of ghosts and would freak out if such a subject came up in a conversation. Whenever he "senses" one, he swiftly recites a chant, casts a spell, or begs for help from a hero, a god, or a famous person (often random, even multiple ones). Yasuhiro is quite gullible, and at first acts laid-back about the killing game, thinking it's some sort of a prank. However, after realizing it is real, he turns much more panicky and he is generally considered useless by the other students. However, he does treat his fellow classmates with general friendliness, going so far as to add the suffix "-chi", an affectionate term for dear friends in Japanese, to the end of everyone's last name. Yasuhiro has quite a cowardly personality and often attempts to trick other people into getting rid of his massive debts, charging incredibly high prices for his readings that, according to other people, often do not fit the accuracy of his fortune-telling. Yasuhiro also seems to possess a smarter, more cunning side despite regularly appearing slow-witted. During his Free Time Events, he attempts to get Makoto to donate his organs so he could pay off a debt without having to dip into his own savings so he could retire in comfort, which causes even the usually trusting Makoto to feel that he cannot let his guard down around Yasuhiro. In Chapter 4, he admits that he has no problem hitting girls who can't fight back and tries to frame Toko for the supposed murder when he thinks he killed Sakura. His attack on Sakura was due to impulsively lashing out due to his fear, but in the end, he takes responsibility for his actions. However, in a desperate move after joining Future Foundation and going on a mission in  Towa City, he pretended to be sick to run away on his own so he could steal valuable items from the area and try to pay off his debt. In Danganronpa 3, he appears slightly braver and shows concern for his friends when they are in trouble, generally feeling more genuine comradeship towards them than before. He manages to survive on his own for quite a while outside the building while being chased by helicopters and in the end, he runs to protect Makoto from brainwashed, armed men despite not having any weapons of his own (though he was followed by Byakuya and his men). It is also notable that while he acts similarly to a con artist, he does possess actual supernatural abilities, as he truly is capable of seeing visions of possible futures. However, it is unknown whether or not he can sense ghosts as he claims. Yasuhiro also has a strange tendency to survive tough situations against all odds. As a somewhat hidden side, he also displays amazing self-trained penmanship and a working knowledge of electronics.
