Crossover high school story involving characters from Yuuki Yuuna is a Hero, Fate/Grand Order, Persona 3 & Momentary Lily, with Yuuna (Yuuki Yuuna is a Hero), Mash (Fate/Grand Order), Makoto (Persona 3), and Renge (Momentary Lily) being members of the Drama Club at Asakura High School in Asakura City. All of them are 18 years old.

This scenario uses crossover characters in an alternative modern-day Japan in 2029. They are members of the Drama Club and all of them are third-year high school students. They became members of the Drama Club since their first year in high school. Asakura High School uniforms consist of a black vest, white shirt, grey necktie, black skirt for females, and black long pants for males, along with having a blooming sakura tree above a burning fire logo on the left side of the uniform vest chest. The logo symbolizes that Asakura is like a sakura tree that keeps blooming no matter what happens, meaning no matter what happens, hope always exists.

Members of the Drama Club consist of:

Yuuna Yuuki (Yuuki Yuuna is a Hero): Class representative from class 3-C. Yuuna is a cheerful, kind, optimistic, and airheaded young girl with a cute face, red eyes, red rose hair tied in a ponytail, small size, B-cup bust, and a cherry blossom hairclip on the left side of her head. She is also the Drama Club leader, as she always loves drama, especially Tokusatsu dramas such as Ultraman and Kamen Rider. Yuuna is always a kind and gentle girl who is willing to help other people in need. Her father is the owner of Yuusha Dojo, a famous dojo in Asakura City. She also loves eating beef and drinking milk. Despite her small bust, she never feels ashamed or lacks confidence, as she always sees people from the inside, not the outside. Yuuna's cheerful personality always helps uplift her friends' and club members' moods. Yuuna is also good at writing stories, even though most of them just use Tokusatsu references, especially from the Showa era.

Mash Kyrielight (Fate/Grand Order): Female student from class 3-B and Yuuna & Renge's best friend. She is a kind, gentle, shy, timid, slightly socially awkward, and empathetic girl with light pink hair of medium length, with her bangs covering her right eye, purple eyes, and a small hair antenna on her head. She has an ample and slightly large D-cup bust size, which she inherited from her mother, Guinevere. Mash is half-French and half-British, as her father, Lancelot, is from France. She also has an older brother named Galahad Kyrielight, who is five years older than her and now works in the USA. Despite Mash's kind and gentle personality, she was born with a weak heart condition, which makes her unable to participate in P.E. classes or high school field trips. She has been hospitalized a few times since childhood due to her heart almost failing. Because of this, Mash's parents and her older brother can be very overprotective, and Mash never had many friends until she entered Asakura High School and became a member of the Drama Club. Makoto is Mash's childhood friend and now her boyfriend. Despite this, Mash is also very good at acting and roleplay and is very smart at memorizing dialogues. Mash always calls Yuuna "Yuuki-san," Renge "Kasumi-san," and Makoto "Makoto-kun."

Renge Kasumi (Momentary Lily): Girl from the same class 3-C as Yuuna. She is a beautiful young girl with light medium-length brown hair and a medium-size, C-cup bust who is also a member of the Drama Club. She is a timid, shy, and socially awkward girl who loves drama and cooking, yet she is always willing to help other people in need. Renge also has a habit of mumbling to herself when thinking about food recipes or drama dialogues. Renge has a younger sister, Suzuran Kasumi, who is more cheerful than her. Renge also used to have an older twin sister, Rinne Kasumi, who died trying to save Renge from a car crash when she was in middle school. Because Renge blamed herself, she always wants to help others as her atonement, despite her younger sister, Suzuran, telling her that Rinne's death was never her fault. Renge can also easily get scared by spiders and other arachnids. Renge usually calls Mash "Mash-chan" and Yuuna "Yuuki-chan."

Makoto Yuki (Persona 3): The only male member of Asakura High School's Drama Club, and he is from class 3-A. Makoto is a scrawny yet handsome boy with medium-length blue hair, light blue eyes, and his bangs covering his right eye, just like Mash. Makoto is a very silent and chill person who rarely talks, though when with Mash, he always becomes more open and friendly. Makoto lost his parents during his childhood on a family vacation when their bus was hit by a gasoline truck. Makoto suffered from survivor's guilt that traumatized him so hard that he used to be very uncaring about his life. When he was treated in the hospital after his childhood tragedy, he met Mash, who was also there after her heart check-ups. At first, they were just silent with each other, but they eventually became close friends after Mash bravely spoke to Makoto. They were separated during their childhood when Makoto had to leave the hospital earlier after being placed in a new orphanage to take care of him. When he entered Asakura High School in his first year, he met Mash again, and Mash immediately hugged him with grateful tears. Makoto is also protective of Mash due to her weak heart condition. Makoto is also good at acting, but due to his silent personality, he usually just plays background characters/NPCs while Mash, Yuuna, and Renge are the ones who always play the main characters. Makoto never has any problem with that, though. Mash usually calls Makoto "Makoto-kun." Due to being the only male member in the Drama Club, Makoto is always joked about as the "Harem MC," despite only Mash having actual romantic feelings for him, while Yuuna and Renge only see him as close friends. Makoto also cares for Renge and Yuuna, though he is always most open when with Mash.
