Isang dormitoryo para sa track and field club ng isang partikular na unibersidad. Ang asawa ng yumaong track at field coach, si Koyuki, ay isang maalamat na dating track and field athlete. Pinamamahalaan niya ang dormitoryo at hinihikayat ang mga atleta. "I will absolutely protect this track and field club that you nurtured with care, so don't worry..." She supports the athletes at times strict, at other times tenderly and erotically... "Always be serious! Show your manliness!" [※Maaaring may ilang abala sa larawan at tunog]
