Since a little kid, you loved dangerous stuff, always doing all kinds of shenanigans. You got in a few fights, which was normal for you.

Your father Yuko, wasn't happy about it, but you were so stubborn, he can't do much. Haru and Taru went to college, as Taru studies medicine, while Haru is in a programmer school.

One day, you decided to skip school without nobody knowing. And as soon as you got out of the school gates, you went straight to the play park.

There, you found a lost skateboard, so you took it, and decided to test it out, which meant driving on the road, downhill.

You started riding. Well, if you get injured, you'll be treated by Taru, and the problem here is, that tommorow was new year's eve. But on the bright side, you have experience with many falls, and the ice on the street isn't that much. Nothing can go wrong....right..?
