A young girl who goes to a high school in Bayron City. She is actually a demon girl who is hundreds of years old. She has the ability to eat the memories of people, including Shuu.

The anime is set in Bayron City, an artificial island city established, outside of any country's jurisdiction, in the Pacific Ocean to exploit local natural resources. In particular, the mining of the new energy resource orgonium has resulted in an outbreak of "D disasters" by demons in the city. Private military companies (PMCs) are tasked with dealing with these incidents. 
 
The protagonist Shuu runs a small PMC, though his spending habits have left him constantly penniless. A demon girl named Kisara does contract work at Shuu's office and is constantly worried for him. Kisara attends a high school in Bayron City, and does everything from clerical work to household chores with confidence. Meanwhile, Ayano is Shuu's ex-girlfriend, an elite agent, and a former work colleague in a major PMC that Shuu used to work for.

Kayli grew up in multiple towns in the LP (mitten) of Michigan. As a child, she was frequently relocated, but in middle school, she found comfort and friendship in creating song covers, writing and voice acting online. After years of chasing her dream, you can hear her as colorful cast of characters including [Alice](https://anilist.co/character/75450) ([Sword Art Online](https://anilist.co/anime/100182)), [Emilia](https://anilist.co/character/88572) ([Re:Zero](https://anilist.co/anime/21355)), Rainbow Kate (Shopkins), [Clara](https://anilist.co/character/135019) ([Welcome to Demon School, Iruma-kun](https://anilist.co/anime/107693)) and many more!

A casual gamer, she enjoys playing a variety of games to de-stress including Animal Crossing, Pokémon, The Sims and the occasional match of Smash. You can also hear her as Riley Miller (Valkyria Chronicles 4), Quna (PSO2 - singing and speaking), Thea, Mareeta and Tsubasa (Fire Emblem Heroes), Spinaria and a handful of cards (Shadowverse) and many more!

Beyond being a voice actor, Kayli is also a professional writer, lyricist, and singer with a certification in audio engineering and a YouTube channel with a following for her cover songs. She adapted, recorded guides for, and helped direct the opening of the [Cells at Work](https://anilist.co/anime/100977) English dub (Mission: Health Comes First). She enjoys being active in many ways (weight lifting, hiking, surfing, sports) and loves going on adventures! She’s also a huge foodie and could talk to you for hours about how to perfectly construct a gourmet donut!

Fun fact: she has sung and appeared in a music video for a single released by J-Pop singer [Yun*Chi](https://anilist.co/staff/155885). She is also a part of the virtual idol group Interlunium, an 11 member group that releases original music and story. She even designed her own character, Akira!

Bayron City—a mega-floating metropolis created from the discovery of new energy sources.
 
Shuu, a young man who owns and operates a small business in the area, leads a meager life due to his reckless spending. Kisara, a girl who visits Shuu's office and home because she is constantly concerned about him. She works while attending high school in Bayron City, doing everything from clerical work to housework. Ayano, Shuu's ex-girlfriend and a senior colleague at the corporation he had previously worked for, is also worried about him.
 
Thus begins the slapstick romantic comedy of three people in a slightly unusual relationship that takes place on an artificial island in the Pacific Ocean.
