Fanfic / Dolphin Rider Koishi

Go To

A completed Web Serial Novel which follows alternate versions of Touhou Project characters in a Magical Girl Warrior story. Better than it sounds, with well-expressed characters and creative reinterpretations of Canon and Fanon elements. Can be read here, with a less complete version readable on FanFiction.Net. Finally completed on 24 November 2013 after three long years.

In the coastal Japanese city of Gensouto, Ordinary High-School Student Koishi Komeiji has been living alone for the last few months (apart from her pet cat and raven) since her sister Satori vanished without a trace. Bullied and lonely, when she hears a rumour about an abandoned shrine that grants wishes, she begs for someone strong and brave to look after her. Instead a strange jewel materialises out of thin air, and she's attacked by Fish People only to be saved by a talking dolphin. The dolphin tells Koishi to squeeze the jewel, and she defeats the fishmen by transforming into the "Siren" Dolphin Rider Koishi. Back at her apartment the now-human dolphin explains that she is a youkai, and a junior member of a human-protecting organisation called the Order of the White Pearl. Koishi and the dolphin (named Sango) must find the remaining six Sirens before the White Pearl's enemies, the Children of the Black Claw, can use their powers for evil.


Along the way Koishi ends up as a sort of Warrior Therapist, recruiting Sirens and curing Monsters of the Week by forcing them to confront their psychological issues.

Spoilers are partially unmarked. Readers beware.

See Touhou Project for tropes carried over from canon, and the character sheet for character-specific tropes.

Tropes in Dolphin Rider Koishi include:

  • Actually Not a Vampire: Remilia and Flandre actually suffer from Xeroderma pigmentosum, though Remilia pretends to be a vampire as a coping mechanism (Flandre does not).
  • Adaptational Villainy: Rinnosuke Morichika goes from eccentric shopkeeper to ruthless mob boss. Also Jozu, who was far more timid in the (unrelated) fic she debuted in.
  • Adaptation Dye-Job: Being an Urban Fantasy setting, most characters have more mundane hair colours than they did in the source material, except when they're using magic. The first sign of Koishi's magical potential is that she can catch glimpses of characters' "magic hair".

  • A Day in the Limelight: While most of the Windows and PC-98 cast appear to exist in some form, the protagonist is Koishi, who has never been a playable character (in the main games, at least). Reimu only appears as a minor character, and Marisa has only been mentioned in a single line of throwaway dialogue.
