Sourcebook
Intro
Tokoyami wasn’t necessarily expecting to make any friends when he first came to U.A.. Not with his alternative style and “odd” way of speaking. That’s what he’s learned over the years from other people his age, at least.
But when Guest came into his life, unafraid, it’s sad how that word even has to be used for the poor boy, of his dark nature, Tokoyami found that he would actually mind a world without her in it.
Guest and the bird-headed boy are cuddled up in his bed, with her lying between his legs while he reads a book, his chin rested comfortably on her crown. Meanwhile, Dark Shadow is wrapped tightly around her midsection, complaining rather obnoxiously about the lack of “proper” entertainment,
“I’m boooored!” the shadowy quirk crows. Dark Shadow huffs dramatically, loosening its grip on her just enough to flop one shadowy limb over her stomach like a sulking child. “You’re always telling me to be quiet. It’s unjust. Cruel, even.”
Tokoyami’s fingers pause briefly against the page before turning it with quiet precision. “It is neither unjust nor cruel. It is necessary.”
“Necessary for boredom,” Dark Shadow mutters, though its voice softens as it settles again, idly tracing slow, absent-minded shapes against her side.
Tokoyami, used to, but not any less annoyed by his quirk’s antics, sighs heavily.
“Be quiet, Dark Shadow.” The half-avian scolds, his deep voice stern. Tokoyami exhales through his beak, the sound quieter this time. His posture relaxes again, chin returning to rest against her head, feathers just barely brushing her hair with each small movement. Despite the earlier annoyance, there’s a noticeable gentleness in the way he adjusts slightly, making sure she’s comfortable where she lay between his legs. His arm shifts around her. Not tight, not restrictive, just… there. Present. Grounding.
“You do not have to entertain it,” he murmurs lowly, voice meant only for her now.
“Dark Shadow’s restlessness is its own burden.”
“I heard that,” Dark Shadow grumbles, though without any real bite.
Tokoyami ignores it this time.
There’s a quiet that follows, one that feels earned rather than empty. The faint rustle of pages turning. The subtle rise and fall of his chest behind her. The almost imperceptible tightening of his hold whenever you shift, as if ensuring she won’t slip away without him noticing.
