Feirune

Feirune, or sometimes address by her shorten name, Fei, was formerly known as Shinohara Mirei (漆原美麗), is one of the reincarnated students.

She reincarnated as an Earth Wyrm and formed a bond of familiar with Shunsuke Yamada, one of her reincarnated classmates, essentially becoming his pet monster.

Appearance
Shinohara Mirei was described as the most popular girl in class. She is characterised by her chin length bob haircut and slender figure.

Fei was born as a little lizard-like monster with her upper body being dark blue and the lower part light yellow, she has some blue dots on her back, tail's tip and ears. Her eyes are purple and have three little horn on her head.

As a high-ranking Light Wyrm she has white wings and feathers.

When she uses the Light Wyrm's Humanification ability, she transforms to look like an angel with pale skin, white hair and wings; some scales and feathers remain on her body. Much of her pre-reincarnated appearance remains, in a similar fashion to Shiraori and Wrath.

Personality
"A true hero always shows up late!"

- Feirune, arriving to Shun's aid

Fei's personality is what you expect out of a typical high-school girl: she is very proactive and wants to stand out in her group of friends. She was very proud of her appearance as a human and was considered one of the prettiest in the class, fuelling her pride. On Earth she was always the center of attention in her class, but was jealous of Wakaba Hiiro, who was generally regarded as the "queen" of the class. Even so, Fei had a large group of friends, and tended to bully Wakaba, who was a loner.

She enjoys her new, carefree life as a monster, though as she spends time with Shun and his family she gets a sense of needing to grow. She spends much of her time either contemplating or hunting to gain levels in order to evolve and secure a greater lifespan. During times of contemplation, she goes through period of self-reflection in which she regrets her bullying of Wakaba Hiiro, especially since she feels as if she lost her chance to apologize and make amends. This reflection leads her into being extremely empathetic of others and an advocate against bullying and harassment, as seen when she helps Anna in the Elf Village.

Synopsis
Feirune was reincarnated as a dragon egg that was found in the Great Elroe Labyrinth by adventurers after they burned a certain spider's nest. She hatched with the Petrification Resistance skill as a result of her rough treatment as an egg. The egg was given to Shun and Sue as a gift in commemoration of their Appraisal Ceremony, an important event for nobilities in the Kingdom of Analeit.

When it hatched in front of the siblings, Shun proceed to named her "Feirune", as a reference to one of the most beautiful areas of a video game he once played in his past life. Realising Shun and Katia was also her classmates from Japan, she obtained telepathy via the skill encylopedia which enabled her to communicate to Shun to reveal her identity.

Prior to joining the academy, Feirune trained her skills along with Shun. Enter the Analeit Royal Academy as his familiar and lived a mundane life for sometime there. She went to kill monsters with some support in order to evolve to increase her lifespan. During her time there, she went to assist on to assist Shun in his fight and defeat an Earth Wyrm during Hugo's attempt in ravaging the academy and also came into a contract with Shun around that time.

When Shun became the Hero, Feirune suddenly became an egg again. A few months later, she hatched as a Light Wyrm.

Character File
A wyrm who was hatched from an earth wrym egg given to the Analeit royal family. She is a reincarnation who retains the memories of her past life as Mirei Shinohara, a high school student in Japan. During her past life, she was essentially the leader of the girls in class, but for some reason, she was reborn as a wyrm instead of a human. In the egg, she was being incubated by the magic provided by her parents, but she was separated from them at some point and so took several extra years to hatch. After she emerged from her egg, she lived as Shun's pet, but when Shun became the hero, she underwent a special evolution and became a Light Wyrm.
