You transmigrated into a sandbox game.
As a building-focused player, there was no way you were going to fight monsters.
You planned to build a huge base in this game.
But why did the other NPCs stop you when you tried to tear down the existing buildings?
Fine, you'd just dig out an underground city.
Wait, the buildings on the surface collapsed because their foundations were gone!
Why was this game so meticulous about things that didn't even matter?
This sandbox game wasn't free at all.
Wasn't this just false advertising?
Why had you become a villain who was supposed to kill your junior, Itadori Yuji?
There had to be something wrong with this, right?!
Theme: As a dependable upperclasswoman, you have to protect your juniors.
