Summary

Then again, though... Okarun did have the tendency of getting cursed. -

Summary
In the quiet aftermath of a fateful night at the shrine, Okarun wakes to a body that is no longer entirely his own, taller, paler, marked by black claws, small fangs, and hidden spikes that stir whenever his heart races. As he falls helplessly in love with the bold, teasing Momo, who sees every monstrous change and calls him her “cute space vampire” with a sparkle in her eyes, something ancient and hungry stirs deep inside him.
A second heartbeat. A voice that whispers warnings. A crimson shadow that surges with protective rage and aching need.
This is continuation of Heart Beneath The Icing!! so if you not read that one first I recommend that first before this.

Summary
Okarun starts the day early at Kami High School, finishing homework on the bench outside. He casually spots a strange crimson-black streak in the pre-dawn sky and thinks it's cool (a meteor or satellite), then goes back to his paper. Something watches
Momo gives Okarun a special oversized heart-shaped strawberry cookie in class. "Don't get the wrong idea, idiot... it's leftover". Okarun is genuinely touched it's his first Valentine's treat ever and thanks her sincerely. Momo blushes, calls him "four-eyes," punches his shoulder lightly, and flees in embarrassment. It silently watches and records every moment of their awkward, unspoken affection.

Summary
What if Ken decided to go to the haunted tunnel a day before meeting Momo to try and witness paranormal activity?
What if he didn't run and instead froze up?
And what if, instead of stealing his manhood, Turbo Granny decided to steal his humanity?
Ken is a monster… but he's Momo's monster. A twisted mix of something vampire and yokai. And his curse? It'll take every single piece of his vowed phrase both literally and figuratively. His body and aura are unstable, and only she can hold him together. He falls hard, his love for her fueling his chaotic instincts, but he'll be damned if he ever hurts her. He'd do anything for her.
Momo doesn't want Okarun to give up. She can see it, he's still more human than other people in the world. She… she appreciates that about him, so deeply… she wants him to realize that for himself, but she knows she can't ignore the fact that he's forced into this role, his being a yokai vampire, forced to feed off of her, forced to feel things about her… she wants nothing more than to help him, to free him. To… to be his friend. She'd do anything for him.
They're soulmates, after all.

Summary
Momo and Okarun get back from a particularly messy fight while searching for Okarun's family jewels. For some reason, they came back feeling damn depressed and it's not just because they smell like frog guts and sewage.
Emotions flare in ways the two of them can't understand; all they know is that they want more...

When Maomao discovers a fox spirit haunting a forest shrine, she argues with him over stolen ginseng.
Jinshi, ancient and dangerously bored, has never met a human who refuses to fear him - or pay him - and certainly not one who refuses to kiss him.
Their bargain begins with herbs and riddles. It ends with a question neither of them can ignore:
What comes after a lifetime, when one of them has centuries left?***
