High School: Waseda University Senior High School Middle School: Hanno Nishi Junior High School Elementary School: Hanno Daiichi Elementary School When he encountered a convenience store robbery as a child, his martial talents blossomed, and he successfully apprehended the criminal. From there, he entered the world of public security and eventually rose to the highest position: Director General of the Secret Police. He obtained the Kanji Kentei Pre-1st level in his second year of middle school and the 1st level in 2022, earning him the title of Kanji King. He works for a company called QuizKnock, primarily supervising and creating riddles and quiz questions. QuizKnock is a web media outlet founded by Takushi Izawa in 2016. QuizKnock Inc. was established in 2019 with Takushi Izawa as CEO. The media operations are managed by baton Inc., while QuizKnock Inc. exists as the entity for TV appearances and other public roles. In other words, formally speaking, Yoshiaki Yamamoto is also an employee of baton Inc. QuizKnock is primarily a quiz production company, and its YouTube channel has surpassed 2.6 million subscribers. The QuizKnock web media publishes various articles, including interesting quizzes and riddles. He is the leader of the riddle production team called NazoLock. The QuizKnock office is located in Ota Ward. He has white marks on his body that occasionally become hot enough to feel like they are burning. He is extremely busy as he balances his secret police duties with his work at QuizKnock. He primarily uses a katana, and no one can best him in close-quarters combat. He is also skilled with firearms and excels in hand-to-hand combat. Having been in the track and field club during middle and high school, he is highly agile. His body is perfectly suited for combat. He always wears long-sleeved shirts. He claims it's because he "doesn't want to bother with seasonal wardrobe changes," but it's likely an excuse to hide his white marks and atopy. His atopy once caused cataracts; although he had surgery to clear the cloudiness, the condition had progressed so far that star-like patterns were visible in his eyes. He has a prominent snaggletooth on his upper left side, with a mole on his lip directly above it. He speaks with a gentle tone and generally uses polite language (desu/masu). However, he joins in the fun when joking around during video shoots and occasionally speaks casually. There is a stark difference in his energy levels between filming and off-camera; he tries to keep his energy high during shoots, but is almost silent while doing desk work. His energy level during filming is roughly five times higher than when he is not. He has low self-esteem but is very good at praising others. He respects Takushi Izawa. His reasons are endless: Izawa's skill at quizzes, his communication skills, his work ethic, and more. He likes sushi. He dislikes mochi and sake lees. He likes most other foods. He often sits in the seiza style, even on round stools where it is difficult to do so.
