What would Ruler do?

— Swim Swim ~ Monologue

Swim Swim (スイムスイム), also known by her real name Ayana Sakanagi (坂凪綾名), is one of the main antagonists of Magical Girl Raising Project.

Swim Swim is a quiet Magical Girl. She is allied with and extremely loyal to Ruler.

Fav LN.pngSwim Swim.jpgFal.pngSpoiler(s) Below!
In Unmarked (Arc 1), she is a secondary antagonist that betrays and murders Ruler. She then goes on to become the leader of Team Ruler. She buys the Invisibility Cloak, costing twenty-five years of her life, but trades it for Tama's weapon.



As a human, Ayana is a little girl with short brown hair tied into two twin tails and brown eyes. She wears a classic Japanese elementary school uniform.

Magical Girl[]

As a Magical Girl, Swim Swim has light pink hair, with short straight bangs, and waves. The front strands of her hair are curly. She also has headphone-like things on her head, which are black with a pink center, fading to purple. The headphones also have a black bunny silhouette on them. Her eyes are purple, fading into pink.

She wears a very generic white swimsuit that sort of resembles a vest, and white pants with pink goggles around her neck. The goggles have a black outline, with white bunny decorations upside down.

She has a black garter with white ruffles and a black heart shaped pattern on her left thigh and a floating belt-like thing surrounding her hips that fade from pink to purple and have bunny silhouettes on them with black outlines. They have long black tentacles with silver pointed things at the back, connected with silver connectors at the top. On her top back, she has small black devil wings.

She has chunky boots on that are black with 4 dark pink shoelaces. The bottom and top of the boots are a violet color with the front of her soles being split up.


Swim Swim is a girl of few words. She admires those in power to the point of emulating her teacher. She tends not to display her emotions outwardly, and is extremely smart for her age, as she was able to manipulate Ruler into a situation where the latter would die.

Swim Swim is very literal-minded and takes the words of those in authority as law. She memorizes all of Ruler's teachings and makes them her way of life, regardless of the content of them.

She believes that she has to follow Ruler's (and, to a lesser extent, Nemurin's) teachings, to the point where she kills Ruler to 'become like her'. Every action Swim Swim takes is an attempt to obey Ruler's words.


Can pass through any object like it's water.

She is able to "swim" through solid objects. During this process, objects will pass through her, and she won't be affected. It allows her to move between substances or invalidate attacks from any materials. However, waves such as light and sound will still affect her.

Special Item(s)[]

  • Rabbits-Attached Goggles: Swim Swim's goggles. its part of her costume
  • Ruler (Former): A magical item. Similar to a halberd, it's a weapon with a blade length of 30 centimeters and a handle the length of 1 meter. It will not be broken easily even when it's used by magical girls. Swim Swim named it "Ruler".
  • Healing Medicine: A magical medicine. It strengthens the ability of those who take it.



Swim Swim is a member of Ruler's team with Ruler as her mentor. Ruler considers Swim Swim to be the most competent of the team. Swim Swim greatly idolized her and would follow every order that she gives without hesitation, with no exceptions. Swim Swim always think about something related to Ruler, even after her death. She names her weapon after her and always asks herself what would Ruler do in any situation.


Yunael and Swim Swim are both students of Ruler. When Yunael died, Swim Swim cared more about how Ruler would’ve handled the situation rather than her death.


Minael and Swim Swim are both students of Ruler. When Minael died, Swim Swim cared more about fighting Cranberry rather than her death.


Tama and Swim Swim are both students of Ruler. Tama calls her "Swimmy" which indicates the affection she has for Swim Swim. Swim Swim cares deeply for Tama and expressed regret over having to kill her.


During Nemurin's Adventure, Nemurin enters Swim Swim's dream, where the latter is shown admiring Ruler and wanting to be like her someday.

Ideal Ruler[]

Top Speed[]

In Let's Play With Top Speed, she asks Top Speed for a ride. During the ride, Top Speed tries to start a conversation with Swim Swim about things like how is she doing in school, to which Swim Swim answers shortly, showing no interest whatsoever. Top Speed offers Swim Swim her friendship.

Despite this, Swim Swim showed no hesitation nor regret in killing her.


Ripple tried to fight her after Swim Swim killed Top Speed. They later have another fight in which Ripple ends up killing her, but losing an eye and arm in the process.

Hardgore Alice[]

Thanks to Minael's magic, Swim Swim manages to find Hardgore Alice's house and plots how to kill her. She decides to kill her while she was going to school in her human form. When Alice discovered her, she starts to run in fear and searches for a safe space to transform, in which she fails and dies shortly after Swim Swim's attack in Snow White's arms.
