You might be kinda like me.

Seisa Mikagura (御神楽星鎖 Mikagura Seisa) is the main deuteragonist of the Mikagura School Suite series. She is representative of the Going-Home Club as well as the headmistress's granddaughter.


Seisa is a girl with long black hair reaching her back, with a red braid attached to a lock of her hair on the left side. She wears the standard winter uniform with a slightly ripped skirt on the lower-left side, black garter belts, thigh-high black stockings, and indoor shoes.
As for her summer appearance, Seisa wears the standard summer uniform with black thigh-highs and indoor shoes. She also wears two monochrome bracelets on her left wrist and a pink polka-dotted wristband on her right wrist as accessories.
In her anime debut, her ripped skirt is replaced by a proper one and she also wears brown school shoes. Her eye color is also lighter than any other media counterpart.


"A member of Going-Home Club, which is an exception? The only thing known is that she’s the granddaughter of the Headmistress, she is girl shrouded in mystery."
—Newspaper Club Memo
The granddaughter of the headmistress of Mikagura Academy [1] who is regarded as a special ability user by many and receives special treatment at school.[2] Seisa always hides herself in the shadows and is rarely seen in school, projecting off an aura of mystery. Despite it making her seem distant and aloof, she is actually an amiable and elegant person.[1][3] She shows signs of having a playful side as well, such as preparing an entire conversation for a voice message for Eruna and often falling asleep while talking or battling.[2][3][4] She even has a funny way to make people notice her when she is ignored in the middle of conversations.
Being regarded as the strongest student at school, Seisa is seen as scary by many when she is in battle. She tends to smile eerily and unconsciously acts in a provocative manner, such as asking her opponents whether they are ready to lose to her or even sleeping in the middle of battle.[2][5] Although this can be interpreted as her underestimating her opponents, she is actually just doing this because she knows very well that her ability is too strong, even for herself, and she gets bored of winning battles easily.[5] The trauma which affected her has also had a strong impact on her personality, making her lose the aspect of fun whenever she uses her ability and her physical condition worse. That's why she always has a medical appointment or bad physical condition as excuses for not making herself appear anywhere.[6]


  • Killing Art: (キリングアート Kiringu Āto)
An ability which can be activated without an item as a media. It's able to overwrite spaces to her heart's content and can be seen as an ability which can do anything in a sense.
