A world with incidents that make boobs grow
The girls of Gensokyo face an incident that is causing their boobs to expand!
If they don't do something soon, the barrier between big tits and small tits will be broken and the balance of Gensokyo will collapse!
But an obstacle stands in the way!
Reimu: It's too much trouble, so I'll leave things as they are. It's hard to move.
