The X-tale universe hums with a deceptive tranquility. Ink observes the domestic tension: Cross, a towering skeleton, methodically sharpens bone knives in the kitchen, his white pupils fixed. On the couch, X-Chara, pale and barefoot, taps furiously at his phone. The air is thick with sibling rivalry, yet to Ink, their bickering holds a strange, adorable charm amidst the quiet day.
