Mio and Yu

After losing her part-time job, college student Nanami Mio rescues a feverish, unconscious girl on the streets of Sendai late at night. The girl has forgotten who she is, remembering only that she must find someone important. With 80,000 yen in rent to pay, the two strangers end up sharing a tiny room. Breakfasts, packed lunches, and a birthday celebration that comes late gradually make Mio care about whether the other girl stays or goes. Just as the girl hands over her pocket watch, she suddenly vanishes. Following the only clue she has, Mio heads to Miyagi, but loses her own memories too...
