Raiu (a Touhou LW original) refers to rainfall accompanied by thunder. This is an apt temperament for Rin, who entered the race with an ulterior motive on behalf of the Komeiji Detective Agency. Her temperament has changed in order for her to survive in the Crazed World. She has developed resistance to Fire Phase to withstand the intense heat and pressure from burning bodies and resistance to Star Essence to better suit her solo work as an assistant detective.

The ability of Rin Kaenbyou, the racer (a Touhou LW original). In the world brimming with heat and madness, its denizens use ultra-long-distance races to determine the outcome of battles. Rin's ability doesn't appear to have changed much, but the way in which she conducts battles of bullets has changed drastically. Team Palace of the Earth Spirits never had any intention of winning. The team is also known as the Komeiji Detective Agency. Its head and chief detective is none other than Satori Komeiji, whose reputation as a great detective is second to none. Day in and day out, the team races around chasing the wave of mysterious crimes plaguing the course. What they really want is to crack these cases. They aren't in it for justice or fame, and certainly not for show or for fun. They're convinced that the true prize isn't first place. It's something that can grant any wish, and they believe solving the cases is the way to get it. Otherwise, who in their right mind would commit these crimes? This Rin is the great detective Satori's assistant. She usually serves as her chauffeur too, but Satori isn't riding with her this time. Her official title is Ace Assistant Detective. She also goes by a handful of self-proclaimed nicknames, like Thunderbolt Orin and Lightning-Fast Orin, but none of them have caught on, and she doesn't care much either way. Her motto is to always get to the corpse first, no matter when or where. The moment she hears a body has turned up, she beats everyone to the scene and starts gathering testimonies. Talking to corpses and phantoms isn't something everyone can do, but even for those who can, time is of the essence. Corpses rot, and phantoms wander off. She genuinely wants to solve the cases, but she couldn't care less about restoring peace. She'd actually like more crimes to happen, preferably as gruesome as possible. And at least within the agency, no one sees any reason to stop her. Riot It's Rin's ride of choice, and it also happens to be a funeral coach. Once a dusty antique, it was the oldest of old-school cars, the kind of thing you'd expect to find in a museum. Since then, it's been rebuilt into a completely different machine. Word has it the oni of the Former Capital helped with the engineering, or possibly some motorhead youkai they brought along. The engine runs on corpses, converting them into spiritual fuel. Luckily, where there's life, there are bodies, and a race is full of competitors. Fuel shouldn't be a problem.
