Fed up with my gloomy everyday life, I ran out into the night without even thinking about tomorrow. I wandered down the dark streets, away from home. After a while, I arrived at a large park. There, strangely enough for this time of night, was a figure holding a skateboard.

...Yeah, it's definitely her. But... She kinda looks like the Uma Musume I saw on TV before, though somehow... the vibe she's giving off feels different from usual.

...Ah. Our eyes met again, boy. Good evening.

...Running away from home, huh?

If you're okay with a big sister like me, I'll keep you company.
