The Anime Lad
Kakeru is a gifted runner who needs somewhere to live. Haiji offers him a room at Chikusei-sou, a worn apartment shared by eight other university students. During the welcome party, Haiji explains that the building is also a track-club dormitory and that he wants everyone to pursue the Hakone Ekiden. Most residents learn this after moving in.

Kakeru can run. Haiji has a dream and a house full of students who mostly cannot. The worn apartment is secretly a track dormitory. The target is Hakone, Japan's prominent university relay. Convince the residents. Face the deadline. Ask ten separate people to share one unreasonable goal.

Haiji looks at a run-down apartment full of ordinary university students and decides, yes, THIS is his Hakone Ekiden team. The confidence is outrageous! Kakeru brings real speed, while most of the housemates bring no running experience and no interest in the plan. That is an incredible starting line for a team sports drama.
Father's Basement
Haiji's recruitment method resembles a housing scam, and reaching the Hakone Ekiden with novices sounds ludicrous. The setup knows both facts. Kakeru has talent, eight residents are beginners, and nearly everyone has reason to resist. The premise earns attention by making persuasion part of the athletic challenge from the first gathering.
