The "future", which should be far away, came when I woke up.
Kiko Hino, 14 years old, 2nd year in junior high school. She fell asleep after an accident, and when she woke up she was 40! Now she is a middle-aged Kiko with the heart of a child. Can she really be a "good adult"... I mean, what is an "adult"!? To all those who have failed to grow up, the author presents an absurd and miraculous rush growth comedy. Start!
