The Ashikabi of the North, and the main protagonist of the story. He has failed college entrance exams twice being unable to deal with pressure. As a result he is seen by others as an idiot and a loser. His life changes immensely when he first meets Musubi and becomes her Ashikabi. As he gains more Sekirei over the course of the story due to his kind heart, he becomes a pivotal and powerful player in the Sekirei Plan.
Above the Influence: Minato is trying his best to remain a gentlemen...even with all his Sekirei hitting on him.
A perverted but good-hearted person that's friends with Minato and the late Takehito. His Sekirei are the twin sisters Hikari and Hibiki. He has supported and come to the aid Minato and his Sekirei many times.
Younger sister of Minato and nicknamed the "Devil Ashikabi", she acquires Shiina as a Sekirei late into the tournament and begins to dominate lower-tier competitors.
Big Bad: How she's seen in the Ashikabi community.
Big Brother Worship: She does it without even knowing she does it. The majority of the reason she likes Shiina in the first place is because of his similar qualities to Minato.
Dirty Old Man: Often behaves like this trying to cop feels on the big breasted women running around.
The Ashikabi of the South. He is rich, spoiled and very demanding. He comes off as selfish and amoral due to how he oursued Kusano at any costs. yet, he's very excitable and cheerful a times.
The Ashikabi of the East and head of a powerful pharmaceutical company. He is ambitious, cold, calculating and the most manipulative of the Ashikabis. He also has control of other Ashikabi along with their Sekirei.
Loophole Abuse: During the 3rd Phase of the Sekirei plan when he brings in more Sekirei and claims it's not breaking the rules so long as they don't fight.
Chiho is a young girl who was confined into the Hiyamakai Hospital, owned by Higa Izumi, because she suffers from an aggressive, incurable virus. She is Uzume's Ashikabi and the reason Higa is able to blackmail her into doing his dirty work.
The Ashikabi of the West. Like Minato, he also cares for his Sekirei. However, he's one of the few, if only, Ashikabi who are willing to join alongside them in combat.
Good Old Fisticuffs: Gets into a lot of fist fights. Start a major brawl in the anime to help Minato out.
Harem Hero: Type 2? Despite the rule against Ashikabi fighting, Nishi is more than prepared to jump into the fray. Especially in the anime, when he and his three Sekirei rush an entire mob.

The MBI clerk for the pharmaceutical department and Ashikabi of the Disciplinary Squad. he has a rather cynical outlook on life and it reflects in his general relaxed attitude towards the Sekirei Plan. He doesn't seem to care for his Sekirei's over all well being but relates well to Karasuba.
Dissonant Serenity: In Phase 3. He remains calm and resumes a conversation with Minato after both had nearly been killed and the battle goes on around them.
The Mourning After: He lost his lover in a war and related his feelings about being angry at the world thereafter to Karasuba. She became his Sekirei as a result.
Mr. Exposition: He tells some important information to Minato.
Nietzsche Wannabe: Explains to Minato how Sekirei die if their Ashikabi is killed. Then asks Minato why he doesn't just kill him to be rid of the Disciplinary Squad that is helping keep the awful Sekirei Plan in play.
While Rome Burns: It doesn't matter what kind of chaos the Sekirei Plan has caused or currently causing. He remains calm and isn't bothered. He's angry at the world and no longer cares what happens to it.
Dumb Is Good: Though the least intelligent of Minato's Sekirei, she's easily the nicest, and the only one who respects his boundaries and/or isn't comically abusive towards him.
Clingy Jealous Girl: Probably the first one to start invoking this trope amongst his harem.
Domestic Abuse: Those water blasts pack enough kinetic force to send Minato flying. If Minato was punching Tsukiumi with that kind of force few would find it so amusing.
Expy: You'd think Tsukiumi was long lost sisters with Satella from Freezing and Sylvie from Princess Lover.
Transsexual: After Minato winged him/her, and since he is heterosexual, his/her body became like that of a female's. S/he still acts and thinks like a male since Minato was given the power to determine Homura's gender and mentality, but chose to let Homura remain who s/he is for now.
Memetic Outfit: Out of all the Sekirei clothes we've seen, from kimonos to battle wear, Uzume is known for pretty much being the most normal looking Sekirei when not in battle mode. Simple jeans and a shirt, not standing out at all.
No Hugging, No Kissing: Other than a few instances, not that many romantic scenes between her and Uzume, sometimes looking more like a sibling relationship than a romantic one.
Slap-Slap-Kiss: This wraps up her relationship with Seo perfectly, zapping him one minute, then making love to him the next, followed by some more zapping.
Evil Counterpart: To Musubi - though they're both hand-to-hand fighters, Benitsubasa's (relative) intelligence and viciousness forms a polar opposite contrast to Musubi's ditziness and sweetness.
Covered with Scars: Apparantly the reason she wears all those bandages...
Evil Counterpart: To Tsukiumi - though they both fight with bladed weapons, Haihane's level-headedness and underhanded tactics form a stark contrast to Tsukiumi's temper and chivalry.
Perky Goth: In spite of her spookier appearence compared to Benitsubasa, she's far less serious.
The eccentric chairman and founder of MBI, and father of Minato and Yukari. Hiroto has completely taken over the city with MBI in order to implement Sekirei Plan in which all Sekirei and their Ashikabi must participate.
Parental Abandonment:It is shown that hasn't been in touch with his children for years or never met them to begin with, he has shown interest in knowing how Yukari turned out to be, but Sahashi doesn't want him near their kids.
Touched by Vorlons: He and Sahashi discovered something during their researches, it also gave them white hair.
Takami Sahashi

The mother of Minato and Yukari, MBI's head researcher, and the person in charge of the Sekirei Plan. She often expresses disapproval over how Hiroto is going about the plan.
Parental Abandonment: Well, she didn't abandon her kids per se, but Minato mentions that she worked a lot, so both him and his sister didn't get to spend much time with her. When we do see her, she clearly has a lot going on since she works for MBI.
Miya's late husband who was friends with Seo. A researcher of the MBI, he was the discoverer of the winging system, Norito, and the existence of the Ashikabi.He was the adjuster of the first generation Disciplinary Squad, Miya, Matsu, Kazehana, Karasuba, and Mutsu. He also did the adjusting for Homura, Uzume, Hikari and Hibiki. Takehito was against the Sekirei Plan and Seo implicates Hiroto in having something to do with Takehito's death.
