All Misuzu Moritani has to do is think about it and, for three minutes, time seems to halt for everyone but herself. But three minutes isn't long enough to go anywhere and come back, especially when you can only do it once a day. So, mostly Misuzu just amuses herself… until she makes the mistake of sneaking a peek up the skirt of a classmate she's been crushing on and it turns out that Haruka Murakami is somehow immune to Misuzu's powers! Oops. And now a really embarrassed Misuzu has to make it up to Haruka. Double oops. Even if it means getting into a "relationship". Wait, what?

And what are the guys supposed to do as they’re pulled deeper and deeper into titillating TILF traps of epic proportions?

The anime takes place in Tokyo in 2030. In a suburban area, suddenly a high-frequency resonant sound is heard, and at the same time a red mist shrouds the area. Anyone who hears the sound, be it human or animal, loses consciousness. The government estimates that it might be an unidentified virus, and fearful of an epidemic, blockades Tokyo and moves its base to Osaka. However, six days after the incident, those who lost consciousness from the sound awaken for no apparent reason. Those blockaded in Tokyo slowly start to get the city functioning again, but after that day strange incidents start to occur at the blockade border. Those who have awakened a hidden blood power arise, are drawn to one another, and must face a cruel fate.
