"Drums are the original instrument. And your heartbeat is the original music. That pulsing beat that accompanies your life is sure to get your body and soul shaking!"
— Raiko Horikawa (The Grimoire of Usami Section 1-5)

Raiko Horikawa (堀川 雷鼓, Horikawa Raiko) is a tsukumogami, transformed from a taiko drum, utilizing the magical power of modern drummers from the Outside World. She first appears in Double Dealing Character as the Extra Stage boss.

General Information

Occupation

Raiko currently serves as the newest 4th member of the Prismriver Sisters' ensemble. Despite being a percussionist, Raiko is the leader when they perform as a group of 4, playing at the center of the stage during performances. Her drumming is popular, even gathering some human fans.

Wanting others to play music with, Raiko reached out to fill in the lack of percussion in the Prismriver Sister's lineup, proving itself successful after a trial session. To make waves in the news twice, the Prismriver Ensemble announced a break-up over "creative differences" after the group decided to be a band of 4, then reformed the band with Raiko's debut three days later. Since then, the band can be seen performing in concerts at the Concert Stage of the Sun.

Backstory

Raiko was born from a taiko drum that had become a tsukumogami through age, but because she was frequently used and enjoyed use, she wasn't a vengeful tsukumogami. During the events of Double Dealing Character, Raiko noticed a strange power enter her body and a desire for revenge against those who used her. Despite her ferocity, Raiko soon realized that the new power she felt was from Shinmyoumaru Sukuna's use of the Miracle Mallet and that it would not last forever. Fearing that she would lose her newfound freedom when she ran out of power, she quickly worked to finding a suitable replacement for it.

Taking a rather large risk, Raiko abandoned her old taiko drum for a new drum kit that had floated in from the Outside World into Gensokyo, cleansing her body of the Miracle Mallet's power and making her self-sufficient. She states that, as a tool's magic power depends on that of its user, the magical power of a drummer is what grants her current abilities. She taught this method to the other temporarily empowered tools, such as Benben Tsukumo and Yatsuhashi Tsukumo, ensuring that they would be able to keep their freedom when the Miracle Mallet's power dissipated.

EX Stage Boss - Phantasmal Percussionist Horikawa Raiko Species: Tsukumogami Ability: Capable of making anything follow a rhythm She's a tsukumogami created from a Japanese taiko drum. She lived for a while, feeling joy when struck by people. However, she began to feel a strong, new magical power within her. At the same time, ferocity flared up in her mind. "Now is the time for the tools to take revenge," she thought. She was wise, though, and quickly realized that this power was that of an oni (i.e. that of the Miracle Mallet). She felt that at this rate, she'd be completely taken over by it. She took a big gamble. She threw away the taiko drums that made up her body, and the drummer that held the magic power, and sought a new magic power of her own. This was in the forbidden outside world, as well. Thus, she obtained a new drum kit, and a new drummer as well. Thanks to the outside world's magic power, obviously. None of the oni's power is left in her body any more. Even if the Miracle Mallet enters its reabsorption period, she won't turn back into a regular tool. She taught this method to the other tsukumogami around her. Even if we're tools, we want to have fun of our own will! Now, shall we go build a paradise for tools?

Character Design

Name

Her surname, Horikawa (堀川), means "canal." It is possible that this name is a reference to "The Drum of the Waves of Horikawa" (堀川波鼓), a joururi play composed by Monzaemon Chikamatsu about a husband seeking revenge after his wife has an affair with a drum player. As another possible inspiration, Otogi-zoushi's telling of "Issunboushi" gives the eponymous protagonist's last name as Horikawa. As Shinmyoumaru Sukuna is descended from Issunboushi, the connection is clear.

Her given name, Raiko (雷鼓), is made up of the kanji for "thunder" and "drum". The kanji used for "Japanese percussion" (鼓) is also the second kanji in the word "taiko" (太鼓). "Raiko" is a set of percussive instruments carried by Raijin on the back, it is used for "lightning" or "thunder".

Design

In Double Dealing Character', Raiko Horikawa is seen with short, wavy red hair, and red eyes, and a black shirt with red cross-hatching that is tucked into a white skirt cut down the middle. She also wears a small purple tie with a white upside-down cross on it, a white sport coat with long sleeves, and a sleeve garter on her right arm. She has black-purple shoes with red lacing and large drum mallets on the back of them.

Raiko's drums are red and decorated with white flower patterns. The bass drum is notably detached from the rest of the drum set.

Appearances

Double Dealing Character

Raiko's sprite in DDC

Main article: Reimu A Scenario

When Reimu finds Raiko in the storm, she explains how she was born as a tsukumogami under the Miracle Mallet's power, but managed to change her own power source. She decides to fight Reimu in order to test it out. After being defeated, she explains a little more about the magic behind tsukumogamis (and tools in general) while promising to not defy the shrine maiden. Reimu, somewhat sympathizing with her plight, says she won't hunt tools and lets her off.

Main article: Double_Dealing_Character/Story/Reimu B's_Extra

Reimu meets Raiko in the storm, and the latter explains how she became independent from the Miracle Mallet's power. Reimu initiates a fight, which Raiko is eager to do to test out her new power. After she is defeated, Raiko promises to behave herself, only asking to be allowed to make a ruckus during concerts.

Main article: Marisa A Scenario

Marisa is greatly surprised at the kind of magical expertise Raiko must have to change out her own source of energy. Raiko explains a bit about how it happens, and Marisa lets her go after she promises not to harm humans, and then leaves to fix her own Mini-Hakkero.

Main article: Marisa B Scenario

Marisa attacks Raiko, as her Mini-Hakkero moving on its own has caused her no end of trouble. After Raiko is defeated, Marisa lets her go, insisting that she has no desire for the outside world's magic. Raiko explains that the tool depends on the user: if the user is wicked, then the tool will be, as well. Marisa takes it to heart.

Main article: Sakuya A Scenario

Sakuya approaches Raiko with her blade in hand, to try and get rid of both problems at once. However, Raiko has already changed her power source and is looking to test it out. After being defeated, she notes that the blade seems to like its "suffering", and offers to show Sakuya how to imbue it with more magic power. The maid refuses, though, as she is worried that if the blade became a tsukumogami, it would be far too strong.

Main article: Sakuya B Scenario

When Sakuya meets Raiko in the middle of the storm, the maid offers to remove the magic power and revert her to being a tool. Raiko has other plans, and does battle with Sakuya in order to test her new energy source. After noting that while mere tools can float in and out between Gensokyo and the real world all the time, a tsukumogami might not follow the same rules, Sakuya offers again, and Raiko turns her down.

Additional Information

• The symbol on the smaller drums is Mitsudomoe. Mitsudomoe are believed to represent the three primary divisions in Shinto, which are "man", "Earth", and "sky", and they are also associated with the lightning god Raijin.
• The hexagonal drum pads are reminiscient of the Simmons SDS-V, the first commercially available electronic drum kit and popular in the 1980s.
• Raiko's Spell Cards "Blue Lady Show" and "Pristine Beat" shoot danmaku as to follow a rhythm, creating a melody out of it. The shot rate is only slightly slower than the beat rate of her own theme.
