Kamigoori Marimo

Kamigoori Marimo (神郡鞠萠) is a Lily who attends Irma Girls' High School for the Arts. She is a member of Legion Hacolberand.

At Kuramayama Girls'
Marimo is one of a group of 13 special Boosted Lilies that were created at Kuramayama Girls' High School of Environmental Science. As part of an experiment to create "a group of Princesses of the Huge that could be an entire Legion together in the future", she and the other test subjects were designated with Roman numerals, from First to Thirteen. Marimo herself was the 13th of them and the final one of the sisters.

As a child, she was small in stature and was loved by those around her, serving as something akin to their mascot. That was in the past; most of her fellow test subjects are dead now. In the same order in which they were numbered, some died in battle, while others were taken away for experiments and never seen again. Up until she escaped from the facility, Marimo was by their side in their last moments, and she vowed that she would carry their last wishes with her and see them granted.

As her companions perished one by one, Marimo lost all hope and became filled with hatred. One day, when she was being taken from Kuramayama to the lab at Sielulintu, she went berserk and was brought to Irmin Lillan Lab for treatment.

At Irma Girls'
In order to carry on the plan that she and her sisters from Kuramayama would create a legion, Marimo sought to fight the Huge as an Irma Lily, but when rumors spread that had been boosted to a terrifying degree, it made it difficult for her to fit in at the school.

However, Himari took interest in Marimo's theory that the Neunwelt Tactic should be performed with the utmost aggression, and spoke to her about it. To Marimo, finding someone who shared the outlook on battle that she had developed at Kuramayama was no less than a dream come true. "It makes me truly happy that you appreciate the way I... no, the way that we fight," she told Himari.

When Marimo was in her third year of middle school, she took part in the Defense of Kiyosumi-Shirakawa, and was among those who pushed back against Tsuzuki Hisui's proposal to abandon the Garden. "If we let them have our Garden, it'll only cost us that much more when we take it back. With me among you, now's the time when being reckless will pay off, isn't it? Fight with me!"

Marimo was not present at the Odaiba Counteroffensive, but she was involved with the differences of opinion that arose among Irma's Big Four when they returned from the battle. Himari began to espouse the point of view of "fighting freely and beautifully," which was not unlike Marimo's desire for a more aggressive Neunwelt, and delighted her to hear. "Let's reach the pinnacle together, Himari!" she said.
