A Detective Defined by Thrift and Cynicism, on a Quest for His Lost Childhood Friend An investigator working at Trigger Detective Agency, with roots tracing back to an orphanage where he grew up alongside childhood friends Yuzuriha Saina and Amaori Natore. Though Kai may come off as rough around the edges and a bit untidy—not to mention his penny-pinching ways—he has a running mouth skilled at talking his way out of trouble. Yet, there's more to Kai than meets the eye. Underneath lies a bedrock of steadfast determination, driving him to stick to his guns no matter the odds. Calm and strategic, he always plans steps ahead. Having been through hell many times over, little fazes him these days. Kai's quest is personal: to find Saina, whom everyone else has given up for dead. Race: Hume* Likes: Alcohol, cigarettes, ramen (without green onions), watching movies, people with convictions Dislikes: Being forced to quit smoking, green onions Skills/Hobbies: Adapting to any environment Losses: Friends, first love *Note: Humans (Hume) don't boast the distinct advantages seen in other races. Their notable edge, if any, lies in a slightly higher reproductive capability than the others.

The Cheekily Charming Junior, Still Wet Behind the Ears as a Detective Apprentice Reiri is the new part-timer at Trigger Detective Agency, bringing a breath of fresh air. Living next door to Kai, she's all about keeping things chill and easy-going, lighting up the room with her bright vibe. Sure, she might miss the obvious now and then, but don't let that fool you—she's got a razor-sharp edge when it counts. Plus, she's got this crafty, sassy side that's hard to miss. Vamps? Yeah, she's not exactly their number-one fan. Race: Hume Likes: Her parents, baseball, cooking, macarons, cherry blossoms Dislikes: Vamps, blood, insects Skills/Hobbies: Can throw a softball 50 meters Losses: Her parents and her hometown

The Princess of a Former Enemy Nation, the Epitome of Purity and an Unparalleled Yearning for Peace Millie, as she's affectionately known, is not only the Vilcar Empire's crown princess but also their newly appointed ambassador extraordinaire to the Frost Neutral Zone. An uncommon voice of moderation within the Empire, she longs for enduring peace with the Federation. An idealist through and through, Millie is earnest and direct to a fault. Her tenacity is admirable, though it can border on stubbornness at times. Race: Vamp* Likes: A peaceful world, reading comics and novels sold in the Federation, her late mother, tomato juice Dislikes: War, horror movies, her three older brothers Skills/Hobbies: Writing novels (the quality remains subpar, though) Losses: Peace, her mother *Note: Indistinguishable from humans (Hume) at first glance, vampires (Vamp) possess an extraordinarily resilient quality. They bounce back from injuries in the blink of an eye, though some are quicker healers than others. Only by severing their heads can one hope to vanquish them. While blood alone sustains their existence, many vamps consume regular food for entertainment and pleasure. Their homeland is modeled after Nazi Germany.
