Eureka is the heroine of "Eureka Seven," as the title suggests. She pilots the world's oldest LFO, Nirvash, and even understands Nirvash's feelings, giving her abilities beyond what you'd expect from a simple pretty girl. Eureka's charms are undoubtedly her cute appearance and mysterious aura! We'll introduce the charms of Eureka that make her different from just another pretty girl!

Eureka is a cool and beautiful girl when she first appears

Eureka first appears in episode 1. When she comes out of the Nirvash, she asks Renton to maintain the Nirvash in a slightly condescending manner. If someone you've just met suddenly asks you in a condescending manner, you'd probably immediately refuse, but Renton is so charmed by Eureka's beauty that he doesn't get angry.

When Eureka came to Renton's place, Nirvash was not working well and Eureka destroyed Renton's room. The next day, Eureka comes to Renton, who is inspecting the Nirvash, and says she wants to do something to make up for it. What a good kid! Renton is also all lovey-dovey... but what he brings out isn't tools, it's a flamethrower...

The powerful words "flamethrower" finally wake up Renton, who was all lovey-dovey. He rushes to Eureka in a panic, seeing the use of firearms that he doesn't think could ever be repaired, but it's already too late. Renton's room has been set ablaze by a fire extinguisher. Renton rushes to the room, but the fire has burned his shoes and he can't even get close.

The first collaboration between the two is in a small, closed room...of course, in the cockpit of the Nirvash. Renton is suddenly forced to put his skills to the test against the Federation Army. Eureka hugs him from behind and tells him, "It's okay, trust me." With that one word, Renton regains his composure... but I'm jealous.

Eureka and Holland come to a parts shop to buy parts for the Nirvash. When Holland picks up the parts the shopkeeper is recommending, he asks Eureka for her comments. Eureka shook her head and said, "The child is already dead." Eureka clasped her hands together, caring for the parts. She looked sad when the parts were treated roughly.

Eureka looks just like Renton, but when she returns to the Gekko, three children call her "Mom" and she lives there. However, none of them look like Eureka at all, and the children are all different races. The only thing they have in common is that they all try to separate Renton from Eureka.

The three of them were trying to get rid of Renton in an attempt to keep Eureka with them, but Renton, who was in a similar situation without parents, approached them and they gradually became closer. The first time the three of them let their guard down with Renton was on a doodle mission to a military facility! Everyone boards the Nirvash and makes a huge graffiti mark on a military facility.

Before working as a member of the Gekkostate, Eureka worked with Holland in a special forces unit called SOF. What Eureka did there was a cruel act that is unimaginable from the current Eureka. She kills people who surrender and kills people who resist. She acts as ordered, and is sometimes called a "dog of the army" by her opponents.

A sad encounter with children

Maurice Maetel Linck. Now the children call Eureka "Mama" and adore her. However, when she first met them, they were the children of people she had killed during her time with SOF. As she pushed through a pile of corpses to make sure everyone was dead, three children appeared, as if protected from within. That was how Eureka first met the children.

"I've changed." Eureka worries about this and has a somewhat hollow consciousness. Eureka speaks to Nirvash as if regretting her change, and loses consciousness when she removes the compact drive. Nirvash then heads deeper into the cave of her own volition. Renton, who found out about this, followed Eureka to the depths of the cave, but what he saw there was a completely changed Eureka.

Eureka managed to survive thanks to Renton's efforts, but the effects of the incident left her with some kind of aftereffects on her skin, and her hair became short. At first glance, it's hard to tell if she's a boy or a girl... Not only does she look like her, but Eureka's inner self also begins to change rapidly from this point on.

Eureka, who has finally been reunited with her, begins to say something like, "I'm Renton..." and blushes. By this time, her feelings had already changed, and she proudly spoke of how "she has changed."

"I want to become more beautiful so Renton can see it." This cute girlish thought caused Eureka's incredible transformation. She studied Taruho and the others intently, taking notes... but the end result was a horrible makeup. Of course, after this Taruho taught her how to do natural makeup, and Eureka safely returned to her usual cute self, so don't worry.
