Imai Seira

Imai Seira (今井星蘭) is a Lily who attends Yurigaoka Girls' Academy. She is a reserve member of Legion Sanngriðr.

She is in the Arsenal faculty and is part of the Sugi class and her specialty is in magus equipments.

History
Both of her parents are CHARM developers, and she had chosen to be an Arsenal since enrolling into Yurigaoka. Her wish is to maintain and develop CHARM for her friends.

Ever since the elementary grade, she is close to Yamaguchi Chihiro who is a year older. At first, it's difficult for Seira to approach Chihiro because Chihiro doesn't open up other than to her closest people.

But during a practice together, Chihiro finally talks about herself and the promise she had with Misaka to start a legion together. Seira praised Chihiro's fighting style and promised to build a CHARM for her.

Later, Seira heard from her friend Misora that in Yurigaoka, promise to build a CHARM from Arsenal holds a deeper meaning. Just like the Schutzengel oath or becoming roommate.

Soon after, an incident happened where Chihiro falls from fighting against multiple small class Huge. While her body is not found, her blood-stained CHARM is recovered, so she is assumed dead.

This changed Seira from her previously cheerful personality into a girl who never smiled anymore. Seeing the gravity of the situation, it is decided to transfer Seira into the Special Dormitory.

It is thanks to consultation with Nadeshiko and Chelice that Seira, who visited Chihiro's grave everyday, finally managed to return to her daily life. To forget her grief, Seira took part in library committee activity, where she became official member once going to middle school. There, she became friend with Ushida Watsuki.

Middle school period
As part of the library committee, Seira also took work with the student council.

Because many Sigrun came from the library committee, and the Yurigaoka Ethic Study Council also gather in the library's meeting room, naturally she also became part of the Sigrun faction.

All of this connect to the Garden's request for her to guide a a new recruit to get used to the rules and tradition of Yurigaoka.

But Tomoyo, spending her childhood raised outside Yurigaoka, often broke the rules such as mistaking the bathroom schedule, straying outside the Garden's walls, or challenging a senior to duel. In all these incidents, the responsibility falls of Seira to teach Tomoyo and clean up the resulting trouble caused. And although Tomoyo would fix her conduct, she soon cause another new problem.

While troubling, Tomoyo's unpredictable action also helps Seira to recover her old personality.

Joining Sanngrithr
When considering about staying as roommate, Seira heard about the declaration of a new legion from Tomoyo. Remembering the story Chihiro had told her, Seira instantly accept the invitation from Tomoyo.

The awakening of her rare skill also made Yurigaoka recommend her to fight in the front line.
