Character Setting

Edit

Lilysa Amano is a passionate and devoted high school cosplayer who only cosplays as her favorite manga and anime character, Lieliel. She is known for her impressive costume-making skills and deep love for "Ashford Chronicle," earning admiration from classmates and the cosplay community. While Lilysa appears innocent and earnest, she is also very open about her love for adult-themed content. One of the key moments in her story is when she realizes and confesses her romantic feelings to Masamune Okumura, her cosplay partner and friend, while on a location photoshoot. Lilysa's journey is full of growth, heartfelt friendship, and personal challenges as she becomes a central figure in both her school club and the larger cosplay world.

Lilysa has short purple hair and wears red-framed glasses.

She is considered quite busty, enough to be envied by some popular models, though not as much as other main characters like Mayuri or Marinna.

Because she is short, it is hard for her to find clothes that fit—shirts that fit her chest are too large elsewhere, and outfits that fit her height are tight at the chest.

She struggles with fashion and is known for having poor taste in casual clothing, to the point where friends worry about her choices.

Usually, friends like Mikari Tachibana help her pick clothes for events.

Lilysa is honest, polite, and well-liked by everyone.

She always uses formal language, even with girls her own age.

She is serious and tends to overthink things or worry when she makes mistakes.

Even so, her sincere spirit draws others in, helping her make friends even among tough or competitive cosplayers.

She used to be independent and handle everything herself, but joining clubs helped her learn to ask for help.

Lilysa loves female characters from manga aimed at men, especially ones with sexy scenes.

Although she is bold in her cosplay, she is shy and childish when it comes to romance—she mistakes her feelings for Masamune Okumura as just friendship at first.

She is a huge eater, able to finish a whole cake or several roast chickens at once, even pausing singing at karaoke when snacks arrive!

Lilysa is a first-year high school student when she first appears.

Her birthday is May 5th.

She is the main heroine in the manga "2.5 Dimensional Seduction" by Yu Hashimoto.

Her cosplay name does not exist, since she uses only her real name and does not use social media.

People who do not know her real name call her "Lieliel" in the cosplay world.

She joined her school's manga research club after meeting Mayuri Hanyu and Masamune Okumura.

Before joining the club, she did all her cosplay work alone.

She has expert-level skills in costume creation and makeup, made even better by her deep knowledge and love for Lieliel.

Lilysa can copy almost any pose or line that Lieliel does in the manga or anime.

Her costume-making and makeup skills are as good as professional custom makers.

She studies "Ashford Chronicle" in detail to make sure her cosplay as Lieliel is perfect.

She is known for staying up all night sewing costumes, sometimes sleeping during class because of this.

She eats and sleeps well, staying healthy even during busy projects.

She is one year younger than Masamune Okumura, attends the same school, and calls on him to take her cosplay photos.

At first, she thinks her feelings for Okumura are just friendship and shared passion, but later she admits she really loves him.

She also becomes close to Mikari Tachibana and Nonoa, with whom she teams up for cosplay events.

She often inspires those around her to be better friends and teammates.

She is unaware of others’ feelings for Okumura, getting surprised only when told directly.

"I really love Lieliel!"

Meeting Mayuri and Joining the Club

Before entering high school, Lilysa meets Mayuri Hanyu at a winter comic event.

After starting school, she visits the Manga Club, where she meets Masamune Okumura, who is watching "Ashford Chronicle."

She feels a strong bond with Okumura and asks him to be her photographer, beginning their partnership.

Early Cosplay Events

With Okumura, Lilysa sells a ROM (cosplay photo set) at an event, but since there is no title or cover, it does not sell.

At the end of the event, a group photo session draws attention and begins building her reputation.

Club Growth and New Friends

Mayuri Hanyu becomes the club advisor, and the Manga Club slowly grows.

The group joins a big cosplay event in Yokosuka.

There, Lilysa clashes with the pro cosplayer 753♡ but, after support from Okumura and Mayuri, makes up and becomes friends with her.

Summer and Further Success

In early summer, Lilysa meets Nonoa at a cosplay shop.

They later join Mikari and Aria Kisaki to do a group cosplay for the Summer Comic Market, playing the "Angel Airborne Squad" from "Lieliel Side Story."

Realizing Her Feelings

During the summer camp, Lilysa finally realizes she loves Okumura after hearing about Mikari's feelings.

She tries to hide her feelings since she believes Okumura will never love her back, but opening up a little helps their cosplay photos turn out great.

Big Achievements

At the school festival, Lilysa makes seven original costumes designed by Marinna for a special project.

She uses her skills to help the group and brings out their best for the festival.

Facing Slumps and New Challenges

After the festival, Lilysa faces a slump after going too long without any new inspiration.

She becomes interested in a popular game called "Witch Girl," worrying it betrays her love for Lieliel, but her friends reassure her.

She joins a big cosplay event for "Witch Girl."

She also meets a famous cosplayer known as Starry Night Princess, and they bond over their dedication to cosplaying.

Lilysa's name comes from "Lilith."

At first, the author planned for Lilysa to be more focused on tempting Okumura, but this role was switched to Mikari, leaving Lilysa with a simply cute name.

Lilysa can bring together all top cosplayers (the Cosplayer Four Emperors) at once, though she does not realize her own popularity and influence.

Her skill stats are listed as:

HP: 53,000

STR: 168

AGI: 28

INT: 3

MEN: 220

DEX: 255

LUK: 168

Lilysa only cosplays as Lieliel and feels that cosplaying as anyone else would not be true to her love for the character.

She once thought not drinking water from a bottle in costume was important to keep the feel of Lieliel pure and only did so when Okumura saved her from fainting.

She enjoys making costumes so much that she often forgets to study, which results in very low grades, but friends help her catch up.

Her dream is to make the "ultimate ROM" of her Lieliel cosplay, and someday she hopes to cosplay as Rastalotte, too.
