Matsu (Sekirei)

Matsu, is one of the protagonists of the story and is Minato's third Sekirei. A computer genius and hacker that lives in a secret room of Izumo Inn, and was once mistaken for a ghost by Kusano. She becomes Minato's third Sekirei. She also likes to shorten people's names and substitute tan for san. Matsu uses a vast network of satellites and spying devices to gather large amounts of information and has even succeeded in hacking the MBI mainframe computer. She refers to herself as the 'Wisdom' Sekirei. However, despite her high intellect, she is very perverse - she uses her resources to peep on people and often tries to 'experiment' with Minato and so most call her the 'Shameless' Sekirei. Matsu serves primarily as Minato's unofficial 'strategist', rarely venturing outside of the Inn and using her vast network of information to aid him. Matsu has the power to access and analyze any electronic device on a telepathic level, but does not have the power to control them. Her name means a "pine" literally. Miya's nickname for Matsu is "Hentai-Glasses". She is being chased by MBI and lives in a secret room at the Inn, because she has stolen Yume's Jinki. Matsu was once a member of the 'first generation' Disciplinary Squad Her Jinki (numbered #2) was a prize for the winner of the second match of stage three.

Appearance
Matsu has long red hair with side plaits and usually appears unfashionable dressed, wearing detached sleeves that resembles a cheongsam and glasses. In the omakes she's seen wearing a piece of cloth to cover her head when she goes to public facilities like hot springs, only in order to avoid the MBI who is actively searching for her.

Personality
Matsu is Minato's third winged Sekirei and serves as his personal source of information (she often refers to herself as the 'Wisdom' Sekirei). However, despite her high intellect, she is very perverse - she uses her resources to peep on people and often tries to "experiment" (implied to be sexual acts) with Minato and so most call her the 'Shameless' Sekirei. This perversion even extends to her interactions with Homura, who would usually retaliate by comically charring Matsu with pyrokinetic flames, and leaving the latter with torched and curly hair (in the anime, her hair becomes an afro after being burned). She has also expressed some sexual interest in Musubi when she accidentally kissed her. One of her more harmless hobbies is watching the mayhem that Minato and his Sekirei cause every day, which started when she was originally stalking Minato. Matsu also often shows her dislike for Minato's lack of confidence, noting that she wants him to believe in his own possibilities and stated in a private conversation with Miya, that Minato, would be the one to change their fates.

Abilities and Powers
Matsu has the power to access and analyze any electronic device on a telepathic level, but does not have yet the power to control them.She also has shown the ability to telepathically communicate information to other nearby Sekirei. The specific limitations of this aspect of her powers is presently unknown.

Her power served different purposes in the past, where she used it to identify several enemy forces and assist the Discplinary Squad during battle. Matsu's ability however is not only limited to her as she stated that there are several other "brain-type" Sekirei that can manage things like breaking through the security of the MBI network. One of them being Kochou, Sekirei No 22.

During the Third Invasion of Kamikura Island, she was able to use her Norito to briefly take control of Kouten and use it to destroy most of the helicopters assaulting the island.
