Year 2021. As part of a promotional tour, Marusya comes to Tokyo and openly gets bored, not knowing what to do without friends. One night, strange things start happening in her hotel room. Trying to figure out what’s behind these inexplicable technical problems, Marusya runs into her sworn enemy. Once, he promised to destroy her—and now, it seems, he has begun to carry out his revenge. But after their meeting, everything turns out completely different… Former enemies didn’t account for the fact that feelings would interfere in their war.
