Tokiko-san got the job of making quizzes/brain-teasers/riddles for Chuukyou Television Broadcasting (a real TV station that airs the anime the fictional character works for). In particular: matchstick puzzles. The show focuses on her trying to make puzzles as well as her early life, family, personality that lead to her profession—particularly her compulsiveness for organization.


Kakeru Miwa is an otherwise ordinary high school student, but a strange twist puts him on the front line in a supernatural battle against the menacing Oni. With the help of a fantastically powerful battle suit known as “Yoroi”, Kakeru joins an elite team that fights the monstrous Oni and defends humanity from otherworldly threats. The team is assigned to protect Oka Myojin, a shrine maiden who is prophesized to save the world, but she must perform a sacred ritual within Shikizakura, the horizon that connects the spiritual and physical world that lies somewhere amid the blooming cherry blossoms and the colorful autumn leaves. But in this world, the journey to destiny is hard-fought, winding and sometimes deadly.<br>
