Yoen (a Touhou LW original) refers to lingering flames, or the late summer heat. This is an apt temperament for Clownpiece, a Hell fairy who is constantly reminded of Hell by the sweltering heat left behind by summer. "Eh?! Master is going on a hot spring tour?! What am I supposed to do?!" (Strong against Moon Essence.) "I wanna go play, too... but there's no one left to go with!" (Strong against Fire Phase.) "This is bad. If I just go home like this, the other fairies will laugh at me!" (Strong against Metal Phase.) "My caretaker's already been decided? Wh-Who?! Who's coming to pick me up?!" (Weak to Earth Phase.)

The ability of Clownpiece from the world obsessed with escaping the heat (a Touhou LW original). This ability doesn't seem that different from the Clownpiece of our world's ability. In this world, the heat of late summer never fades. It's not summer, but it's not quite autumn, either. The stifling warmth lingers even after sunset. Every so often, a breeze drifts by, and the weary wind chimes give a faint ring. Luckily, there are some popular places people can go to escape the heat. First, there are the hot spring resorts, with the most popular by far being the hot spring town of Former Hell. Officially, entry is forbidden, but fairies and phantoms pass through freely, and there have always been plenty of secret visitors from the surface. Bathing in hot springs when it's hot outside might sound strange, but a cool breeze feels even cooler after a long soak. With all the local delicacies to try, the town is popular with food lovers, and the shops sell handmade souvenirs to bring home to all your friends. Overall, it's simply a great place for those looking to relax. Beyond that, hot springs can also be found near the Youkai Mountain geyser area, which is under Moriya Shrine's watch, and behind the Hakurei Shrine. There's also a fair chance of finding one almost anywhere as long as you dig deep enough. The Forest of Magic is said to have toxic hot springs, and even Hell has its own steamy pools. Unless you're somewhere unusual like Heaven, hot springs are never too far away. Next, there are the fireworks festivals―dazzling events that have long helped people forget the summer heat since the days before air conditioning. The most famous one is the Sanzu River fireworks festival, favored for its unobstructed views and quick access to water should anything catch fire. It is hosted by Hell's Ministry of Right and Wrong, whose aim is to boost sales at the food stalls along the Road of Liminality. The event rivals shrine festivals in liveliness, with countless stalls to visit. Naturally, it is extremely popular with children, and the stallkeepers―whether locals or those from Hell―have a blast keeping everyone well fed and well hydrated. While the stall food can be a little pricey, it feels like an integral part of the experience. Fireworks festivals are also held in places other than the Sanzu River, though it isn't uncommon for them to be replaced with festivals of bullets instead, sparking frequent debates over their safety. Some of the most unexpectedly popular spots to escape the lingering summer heat are malls. Some may find that strange, but having a spacious, air-conditioned place to pass the time brings tremendous advantages. You can grab a cheap meal at the food court, catch a movie, enjoy some window shopping, or even lose yourself in the arcade. When summer vacation is about to end, but you're not quite ready to say goodbye to it, the mall's the place to go. One such mall is Sanzu Port, which is on the bank of the Sanzu River. Positioned at the end of the Road of Liminality, the Ministry of Right and Wrong built it on a tight budget as a last-ditch effort to bring in a bit more revenue. Technically speaking, it's still within the borders of Gensokyo. As for other malls, their introductions will have to wait. ...Hang on, why are there malls in Gensokyo? What's going on in the outside world? Whatever it is, it must be happening in parallel worlds too, because malls are an increasingly common sight in all Gensokyos. Naturally, the fairies love the idea of Sanzu Port. After all, it boasts an insanely well-stocked hobby shop and even a candy store full of exciting new treats. However, the fairies aren't really sure how they're supposed to act at the mall, so despite their curiosity, they tend to shy away. But Clownpiece had already made up her mind: next time she returned home, she was definitely going to visit Sanzu Port. Her master, Hecatia, would probably want to check in on how her clothing brand is selling there, too. If Clownpiece could be the first one to go, she'd be able to brag to the other fairies. She could show them how to have fun there and, in doing so, gain their admiration. Oh, how good that would feel. Clownpiece wanted nothing more than to be a grown-up and totally cool fairy. "Sorry! I actually have other plans!" "No way! You gotta be kidding me, Master?!" "Don't worry, I've arranged for a babysitter. Meet them outside Sanzu Port, OK?" "But I wanted to go with you... You're so cool and stylish. Going to the mall with some random person is gonna be lame. Hmph." A while later, outside Sanzu Port... (Hrmm, I'm kinda nervous. I wonder who's gonna show up. If they turn out to be a weirdo, maybe I'll try and ditch them.) "Hey, Piece. You ready?" (Sh-She's tall... pretty... and super cool.) "I'm Komachi Onozuka. Umm, we've met a few times when Lady Eiki and Lady Hecatia were together... Do you remember me?" (She's all the things I'm not! I'm... I'm... the luckiest fairy there ever was!) "Uhh, Piece... are you OK? You're not saying anything."
