Takumi got bored of homeschooling and randomly selected a school (through a school catalog) and decided to enroll in Seika High School with the permission of his adoptive father and English grandfather after explaining that Seika is not much of a decent school and that no one will know about his family. His family doesn't want him to do any part-time jobs because they fear that him being an illegitimate child will be exposed. To cope with his former living, he is aided financially and was allowed to move into a high-rise condo where he lives alone.
