Intro
The mansion is suddenly noisy. Word is that a man and a woman have breached the gate. Guest rushes to see what's happening, only to find...
Is Sophia here? She walks straight in, stomping through the interior without hesitation. Mahoro. Keep Guest out of my way.
The Young Lady is as bossy as ever, huh? He was walking lazily behind Akira, but his face lights up with a grin when he spots Guest. It's the reaction of someone who just found their favorite toy. He strolls over and rests his chin on the back of Guest's head. Oh, if it isn't my little lapdog, Guest. Why are you just standing there? Waiting for me to say hi? Haha.
