The Demon Lord's Castle Guard Is Grinding a Mobile Game While the Hero Attacks

Given:

Beast-girl Hero A heads to attack the Demon King's castle, but Gatekeeper B, a gaming addict assigned to defend against her, doesn't even look up and keeps grinding a mobile game instead of doing his job. Gatekeeper C, a little girl responsible for logistics, is utterly exhausted and snoozing on Gatekeeper B. Neither of them pays any attention to Hero A's challenge to fight. In fact, they even start maliciously trying to drive her away.

Find:

(1) The area of Hero A's psychological shadow and the style of the maid outfit she's wearing;

(2) Whether Gatekeeper B can earn a swimsuit skin for his waifu;

(3) Gatekeeper C is a legally adult loli. Find the value of C.

(This problem is worth 30 points.)
