Tsukasa (boyfriend)

previously partnered with Kazuki Kuwanomi. After her partnership with Kazuki was dissolved, she became the partner of Tsukasa Mizugaki. After gaining her memories back due to a new experimental OS (which fixed the 81,920 hours data corruption) and with additional nanobots that extended her lifespan to indefinite, Isla began playing Gun Gale Online with Tsukasa Mizuaki. She is known as IONIA in the VR game. Isla is also one of the highest rank female players in osu!. She is the first iteration of Giftia X (which is stands for Infinity [Eternal Life]).


Isla was introduced as showing almost no emotion, but has since developed more. She is very innocent, and often has difficulty understanding how social situations should work. When it comes to Tsukasa, Isla becomes jealous easily and is eager to be impressive and useful to him.

Isla cares deeply about the feelings of others. It has been stated that she was the first employee of Terminal Service #1 to cater to the needs and emotions of her clients. The rest of the staff later followed Isla's example at Kazuki's request.

After getting upgraded to Gifitia X after her retrieval, she becomes even more human-like, even to the point that she gets jealous easily when she sees Tsukasa doing thing with other girls. She still says "Error" when she gets annoyed. Isla is known to others to be the most human-like Giftia active (even more so than normal Giftias).

Power Level[]

Tier: 10-B | 6-C

Giftia | Giftia X


Dynamic Limiter - Unlike Isla's previous OS, Giftia X allows her to turn her limiter on and off, shall the need arises.

Self-Maintenance - Giftia X introduced nanobots with the new OS, removing the need for maintenance.

Self Charge - Shall Isla batteries run too low, she will fall asleep and begin recharging, based on the amount of charge she needs. Like humans, she will sleep on a normal schedule most of the time.

New Abilities introduced once Isla is upgraded to Giftia X:

  • Hand Sonic: Calls forth a single blade or a pair of blades, one on each hand. The blades are capable of slicing through steel or even easily dispatching Shadows. It has been shown to have many variations:
    • Hand Sonic [Version One]: Regular shape resembling a longsword. The main version she uses when fighting.
    • Hand Sonic [Version Two]: A thinner, longer version than the previous. It has a curved-diamond shape on its tip. She made this version thinner for higher speed.
    • Hand Sonic [Version Three]: Is shaped like a traditional sai. She once remarked that this version is "inelegant".
    • Hand Sonic [Version Four]: A variation which is shaped like a lotus flower with no edges other than, perhaps, its petals. Apparently more of a bludgeoning weapon than a slicing one. Isla admits to have created it in her attempt to make her weapon "cuter".
      • Hand Sonic [Version Five]: Isla's most recent variation of Hand Sonic (Excluding the version in the 3rd Drama CD). It is basically a pair of pincers secured on the arm by a violet gauntlet-like accessory that resembles a demon's head, horns and shape. She created this version due to Tsukasa's advice that she should give herself a more defensive weapon. She also used this version as a makeshift slingshot and for dispatching threats or hitting certain targets from afar.
      • Hand Sonic [Version Twenty-Eight]: This is Isla's latest version of Hand Sonic. However, this variation is only known to have been used as a last resort. Tsukasa has stated that it excels in bringing pain and that one would merely know just by looking at it
  • Distortion: Allows her to deflects bullets and other projectiles away using an invisible shield in front of her. The drawback of this skill is that she has to take it down should she want to switch from defense to offense.
  • Delay: Creates a sort of after-image for close range. It is effective in dodging melee attacks by confusing the enemy into attacking elsewhere.
  • Harmonics: Makes a clone of herself which is identical to her, except it has blood-red eyes. Clones created through this ability have their own consciousness, as well as all the abilities of the original - including Harmonics itself. The copy are forms of whatever she is feeling at the moment of their creation.
  • Absorb: A "hidden ability" which acts as the reverse of Harmonics. It allows the reintegration of clones created through Harmonics into her body. This, however, poses some risks as Harmonics clones also possess their own consciousness. This ability is connected to Harmonics using a command called timewait, which is simply a wait command which delays the execution of this ability. This ability was created by Yuri as method of dealing with the Harmonics clones.
  • Overdrive: A passive ability that gives her superhuman strength. The word "Passive" is supposed to refer to a fact that, unlike other guard skills, this skill can be used without an explicit invocation. Overdrive's passive effect is strong enough to lift a whole army into the air by jumping.
  • Howling: Emits powerful high-frequency, high-amplitude sound-waves from crossed Hand Sonic blades, meant to make an enemy faint. Created by one of the Harmonics clones.
  • Angel Wings: Sprouts wings from her back that, while they don't enable her to fly, can be used to slow her descent. They also allow her survive long drops, such as jumping from the roof of a building.
  • Sonic Rotation (unnamed): This technique when activated, produces a blue aura when used. Isla produces a Version One Hand Sonic on each arm and spins rapidly, effectively destroying everything in the vicinity. It was stated to be as powerful as a jet bomber by Tsukasa, after it demolished a fulled armed force from the SAI.


Tsukasa Mizugaki - Tsukasa was very kind to Isla from their first meeting. Isla has feelings for him, but after Tsukasa confessed his feelings for her, Isla rejected him at first. The main reason was that Isla decided that it was better if they stayed away from each other because Isla does not want to gain anymore happy memories. However, after Kazuki persuades Isla, she finally agrees to continue her relationship with Tsukasa and confesses her feelings to him. She promises to do anything she can to make Tsukasa happy until the end of her time. When she became Gifitia X, she began playing GGO after Tsukasa introduced her to the game. They are madly in love and regularly participate in Squad Jam. However, she still has the job of retrieving past generation Gifitas with Tsukasa, and are officially boyfriend and girlfriend.

Kazuki Kuwanomi - Isla has great memories with Kazuki during their first time partnership. But after retrieval of Michiru's Father and lost Kazuki her leg, Kazuki decided to dissolved their partnership, thinking it is better for Isla. Kazuki realizes that was wrong to be like that. So, during Isla's second partnership with Tsukasa,Tsukasa persuades her to understand her current and the similar situation from when they were partners by telling the reason why their partnership was dissolved in the first place. She came to realize that and thought of staying with him. Eventually, Isla worked up the courage to face Tsukasa and declare her feelings for him.

Michiru Kinushima - Isla has admitted to Michiru that she has feelings for Tsukasa, saying that her heart begins to pound and that she starts to feel confused whenever she thinks about him. Isla always asks for advice from Michiru about her relationship to Tsukasa.
