Kamen Rider Fan Fiction Wiki
This article is about a/an rider in Kamen Rider 555.

Alicia Kasey is the tritagonist and the first secondary rider of Kamen Rider 555. She is a young woman who dealing with an abusive father alongside her mother and little mother. When she became an adult, she met Sydal Sabin and Smart Lady and creates the Rider Crew alongside Sydal as Kamen Rider Chi as the current user of the Chi (Χ) Gear to fight the Orphnochs when she witnessed his sister and all of her friends were hurt.



Alicia had a good childhood but it could have been better if her father wasn't so abusive. The reason why her father was abusive is that he never wanted children because he doesn't want to be a part of the responsibility/struggle of raising children. He got depressed and started drinking. Many times he gets drunk and hits Alicia and her mother. When Eliza was born, it got her father angrier. Alicia kept protecting her because she doesn't want the abuse to affecting her in the future. When Eliza turned 2, her dad and mom divorced and moved out. After that, her mother asked her to forget what her dad did and move on. And she should be a nice person and treat everyone the same.

Kamen Rider 555

Meeting Sydal Sabin and Smart Lady

Alicia was captured by the Orphnoch that want to lure the Kamen Riders. Her sister Eliza wasn't able to find her so a young man named Sydal Sabin helps her. Sydal wanted to help her because he noticed that she was crying alone and sad. The Orphnoch shows up with Alicia hostage. Sydal saves her as Kamen Rider Phi and Alicia reunions with her sister. She also introduced herself to Sydal Sabin.

The next day, Alicia and Eliza were involved with the Elephant Orphnoch attacking people. Sydal finishes the Orphnoch and was going to leave. But Alicia insisted on taking Sydal home for saving her two times. When Alicia and Sydal went to Smart Brain, Alicia met Smart Lady. Alicia asked Smart Lady on how does the Rider Gear work explaining that she built the Rider Gear to fight the Orphnoch because the Orphnoch were confident in their power, they want to rule the world. When a lot of the backstory was explained, Alicia wanted to know more but Sydal had to fight the Orphnoch again. After the fight, Sydal takes Alicia back to her house. Then Alicia kissed Sydal on the cheek, showing her affection to Sydal.

Creating the Rider Crew

Alicia showed up in Smart Brain to help out, where Smart Brain suggested that Sydal needs some friends because he is lonely. Alicia just happens to be noticed by her friend Kumiko and introduce her to Sydal. Alicia asked Kumiko about where are her other friends. They ended up finding her friends (Ethan, Alyssa, Austin, and Jacqueline) in a park and she introduces them to Sydal as well.

Sydal was attacked by the Ox Orphnoch and was overpowered so Ethan, Alyssa, Austin, and Jacqueline intervenes but they got overpowered as well. When Smart Lady showed up with the Phi Gear, she got attacked dropping the Phi Gear. Alicia retrieves the Phi Gear and tried to transform but it failed because the Rider Gear Pass doesn't have her DNA. When Sydal transformed, everyone shocked by the sight of Sydal being Phi besides Smart Lady and Alicia.

Alicia alongside with Kumiko got grabbed by the Ox Orphnoch so Sydal had to hold back a bit until Ethan and Austin managed to save them. Sydal takes everyone to Smart Brain so they can heal their wounds and was told how serious fighting the Orphnoch are. After everyone is healed, Alicia had an announcement about they should form a team so they can assist Sydal against the Orphnochs with Smart Lady coming up with a name called the Rider Crew.

Becoming Chi

When Eliza shows up to Smart Brain, Alicia was actually in a fighting simulator so she can defend herself against the Orphnoch but Smart Lady was preparing her to become Kamen Rider Chi and Sydal knew about it. After they were finished, Alicia noticed Eliza and Eliza gives her and Sydal big hugs. Eliza was wondering about where was Alicia was with Alicia explains that she been a little busy about trying to help Sydal in the fight against the Orphnoch.

Eliza instantly said that their mom has been worried about her because she has been gone. Alicia said that she is fine and they don't need to worry and explaining how did Sydal meet everyone else and that Alicia and Smart Lady want Sydal to meet friends because he needs more human interaction and he may need friends so they can fight the Orphnoch. When Sydal got injured in a battle against two Orphnoch, Alicia and the other members of the Rider Crew came to fight the Orphnoch while Kumiko and Smart Lady are trying to help Sydal.

Sydal was about to be destroyed by the Orphnoch but Eliza gets in front of Sydal protecting him. Sydal was able to take a hit from the Orphnoch that was meant for Eliza but she still got hurt in the process. Alicia saw what happened and gets enraged wanting to fight but Smart Lady threw something at her, turning out to be the Chi Gear. She seems to be confused but she uses the Gear anyway and becomes Kamen Rider Chi, shocking everyone that was nearby.

She goes all out on the Mantis and Cactus Orphnoch putting up a better fight than she thought. But her anger from the Rider Crew being attacked and her lack of fighting experience compare to Sydal, she didn't stand better than Sydal. But she was saved by the Rider Crew so they can retreat with Smart Lady taking an injured Sydal and a hurt Eliza back to Smart Brain while the Rider Crew runs away.

Alicia is angry at herself for not protecting her sister. It was her responsibility to take care of her but she is glad that Sydal protected Eliza from any further damage but Sydal got injured and couldn't move an inch. Alicia kept saying that she should have saved her. Sydal just barely woke up saying that she can't change the past and Eliza will be alright. A day later, Alicia confronted the Mantis and Cactus Orphnoch for revenge on hurting Eliza and Sydal. The Orphnochs wants to go after Sydal but Alicia said "if you're going after Sydal, we'll have to get past me first".

Smart Brain Duo between Chi and Phi

The Orphnochs and Alicia as Chi were charging each other and started fighting. Alicia tries her best to hold them off by using her weapons Alicia was just deformed from Kamen Rider Chi, she was about to get destroyed but Sydal shows up just in time. Sydal said that Alicia doesn't need to be angry anymore and what happens in the past will not affect her anymore and Eliza will be fine and lucky that they were on her side. He promises that Eliza will be happy and safe in the future. Sydal and Alicia transform into Kamen Rider Phi and Chi together and teams up against the Orphnoch in one taking on the other. Phi and Chi finish the Orphnochs off with their Rider Kick finisher.

After that, Alicia and Sydal go to her mother's house so they can see if Eliza's alright. When they went into the house and saw Eliza, Alicia ran toward her and gave her a hug. Alicia told Eliza to let the past go so it won't interfere in the future. Sydal suggested that she shouldn't get involved in their battles against the Orphnoch because she would get hurt again. Eliza agreed with the suggestion and hugs both Sydal and Alicia. Then Sydal and Alicia leaves the house and goes to Smart Brain.

Kamen Rider Chi

Rider Statistics

  • Height: 189 cm
  • Weight: 95 kg

Ability Perimeters:

  • Punching Power: 3 t.
  • Kicking Power: 7 t.
  • Maximum Jump Height: 30 m.
  • Maximum Running Speed: 100 m. per 6.3 sec.

Alicia transforms into Kamen Rider Chi utilizing the Chi Gear Pass so she can authorize the Chi Gear, which allows him to use the Chi Driver and then inserts the Chi Phone to the driver to transform.

Once the transformation is completed, the Chi Armor has several key features in its design to protect protection to the user. Like all Rider gears, the Chi armor manifests when the Chi Driver generates only after the wearer transforms.

  • Sol Foam/Metal: Soft parts of the armor are made of Sol Foam, & the hard parts are made of Sol Metal. This substance is generated by the Chi Driver to form complex machinery that is powered by Photon Blood. If the Foam or Metal are damaged, the armor switches off & resets itself.
  • Fullmetal Lung: The chest armor of the Rider provides the most protection, being able to withstand Anti-tank weaponry. It has a structure in which two shock-absorbing bags are sandwiched between four layers of Sol Metal, allowing the heavy armor to repel tank fire. There is also an oxygen tank attached that can provide up to three hours of oxygen.
  • Photon Blood: A glowing yellow plasma substance that provides all of the Rider’s powers and generates all of the physical features of the armor. The Photon Blood is generated from the Chi Driver.
  • Photon Streams The yellow lines running all over the body. It is an energy flow path that contains the fluid energy Photon Blood which is yellow for Chi. Every suite developed by Smart Brain has Photon Blood, each one with a different color.
  • Photon Terminals: Where the Photon Streams connect with the gauntlets & greaves.
  • Global Feeler: The antennae. They communicate with the artificial satellites Eagle Sat and Hawk Eye that support Kamen Rider Chi's systems. They can collect information as well as download new programs.
  • Energy Holster: A holster on the lower right leg. It is an energy amplification terminal that is used to mount the Chi Pointer whenever Chi wishes to execute the Gold Smash Rider Kick attack.
  • X Finder: The large eyepieces of the Rider give them the incredible vision. They can see in darkness with no problems & have an unlimited amount of X-ray vision.

This form has three finishers.

  • Pressing "Enter" on the Chi Phone allows Chi to execute an "EXCEED CHARGE" attack, depending on the item he inserted the Mission Memory into; sending a burst of power from the Chi Driver along the Photon Streams to the weapon in question, giving it a tremendous power boost, and in some cases extra abilities.
    • SB-913C Chi Shot finisher:
      • Grand Impact: By inserting the Chi Mission Memory into the Chi Shot, Chi throws a punch powered by the energy inside the Chi Shot.
    • SB-913B2 Chi Pointer finisher:
      • Gold Smash: By inserting the Chi Mission Memory into the Chi Pointer, Chi produces a pair of overlapping yellow energy drills around his foot and toward his target, jump to the target for a dropkick as the deathblow.
    • SB-913X Chi Blade Gunner finisher:
      • Chi Slash: By inserting the Chi Mission Memory into the Chi Blade Gunner, Chi fires a constricting energy net from its gun section, while simultaneously over-charging the sword section and temporarily increasing Chi's speed for a dashing strike. It is important to notice that the blade of the Chi Blade Gunner does not cause damage by itself, but due to the energy that it discharges once in contact with the target.

Accel Form is Chi's super form where he can now move at the speed of sound for usually 10 seconds, his physical attacks also become 1.5 times stronger & he can perform a new variety of his regular finishing techniques.

The wearer must be in Chi’s basic form to transform, with the Chi Accel watch attached, transferring the Accel Memory from it to the Chi Driver. When this is complete, the Full Metal Lung chest plates will rise out of their recesses & rotate from the scapula to form shoulder pads & reveal the Chi Core in the center of the chest.

The Sol Foam remains black, while the Photon Streams turn silver & the Ultimate Finder turns red & "Start-Up" begins. Once Chi has reverted after "Time Out", the Mission Memory keys are returned to their respective holders. The transformation usually fatigues Chi & has never been done 2 times in the same scene.

This form has three finishers.

  • Pressing "Enter" on the Chi Phone allows Chi to execute an "EXCEED CHARGE" attack, depending on the item he inserted the Mission Memory into; sending a burst of power from the Chi Driver along the Photon Streams to the weapon in question, giving it a tremendous power boost, and in some cases extra abilities.
