Summary
Liliana Braveheart, an Irish exchange student and amateur MMA fighter, arrives at Karasuno High hoping for a quiet academic break and a clean escape from Ireland’s paparazzi. Hosted by her pen pal Kiyoko Shimizu, Liliana quickly learns that breaking the language barrier might be harder than breaking bones—but it's connection, not fluency, that really counts.
As she stumbles through cultural mishaps and unexpected friendships, Karasuno’s quiet powerhouse, Asahi Azumane, finds himself drawn to her fierce spirit—one that reignites something in him he thought long gone. Between early farm mornings, volleyball antics, and decoding love letters from her shoe cubby, Liliana starts to realize she may have found more than just a temporary home… and that love, like language, doesn’t need to be perfect to be understood.

Summary
This is a crossover story between my works: 'Friday the Thirsteenth' and 'The Star in a Poisoned Sky.'
Summoned into the Clover Kingdom by an unknown devil, Azalea is an enigma wrapped in blood and shadow. Bound to abyss magic and marked by a five-leaf grimoire, her very existence testifies to the presence of devils. Though she is a murderer and a criminal by nature, her vampiric physiology grants her a singular, dangerous gift: the ability to consume curses by sinking her fangs into the afflicted, drinking away both blood and blight.
Torn between her own darkness and the role the Clover Kingdom desperately needs her to play, Azalea becomes both a threat to fear and a weapon too valuable to discard.
