Marisa shook her head as she awoke to the sounds of water and creaking wood. Surveying her surroundings, she found herself inside the hull of a boat. She attempted to stand up and the shifting of the boat almost destabilized her. A loud snore came from behind her. Marisa looked over her shoulder to see a young girl with red pigtails sleeping behind her. The girl was carrying a large scythe. Marisa raised her eyebrow in curiosity. Turning around carefully so as not to rock the boat, she took her finger and licked it. She placed it in the girl's ear.
"AAAAAAH!" The girl screamed, causing Marisa to fall backwards laughing. The boat rocked back and forth and the pigtailed girl fell out of the boat screaming and into the cold waters of the river. Marisa stood up and peered over the edge of the boat. The girl was floating at the surface of the water, her teeth chattering.
"Glad to see you can swim!" Marisa said, laughing at the girl.
"Oh yeah? Let's see how you like it!" The girl swung her scythe through the water and slammed it into the bottom of the boat. The boat began sinking.
"Hah! I can fly!" Marisa jumped, but nothing happened. "W-what?"
"Nice try. This is the Sanzu River. There will be no flying."
Marisa cussed under her breath and then groaned as her dress started getting wet from the water of the river draining into the boat.
"So Komachi, who's going to be paying for a new boat?" A voice called from above. Komachi gasped and hid underwater. Above them floated the Yama, Shikieiki Yamaxanadu herself.
Komachi bubbled sadly in the waters. "You're lucky nobody else will work for me. Now, Marisa, I will grant you your flight abilities if you will follow me to court."
"Sounds fair enough." Marisa winked at Komachi and then flew into the air, following Shikieiki away from the scene.
"Wait, what about me!?" Komachi exclaimed as the last of the boat sunk under the water.
Marisa descended onto the other side of the Sanzu River with the Yama.
"Heh, you're a lot shorter in person." Marisa commented.
"You make remarks like that and court won't be necessary." She responded, and the two walked into the courthouse.

Reimu dropped to the ground, dodging a swift jump attack from Youmu. There were talismans flying everywhere, catching trees and flowers on fire and exploding in the air around Youmu. Youmu's ghost half was swishing back and forth in eagerness, watching the action. Reimu's bandages had come loose in several spots and her hair was a dark black from when an explosion had slashed at it with its fiery tendrils.
Youmu darted forward, her swords slashing a nearby talisman, causing it to spin mid-air and explode next to her. She used the force of this blast to rocket herself into the air. Slashing her way towards the shrine maiden, she cut a path and aimed a good kick at the girl. Reimu dodged the kick, but a slash to the side got her and she fell to the ground in pain. "Heh, not bad…"
"Your spells are a nice distraction, but I don't see much fighting from you, Reimu." The girl said, licking the blood off her blade.
Reimu glared at this, and rushed at the girl as she had her tongue up to the sword. She pushed the sword up against Youmu's mouth, tongue still extended. "I can be a fighter if you'd like." Youmu glared at the shrine maiden. The sword began to glow blue and suddenly a large shot of energy came bursting out of it, slamming into Reimu and sending her flying backwards.
"That's the Heaven's Sword technique. I wouldn't underestimate it."
Reimu wiped the blood off her hands with a bit of cloth from her dress. "I hadn't planned on it."
Youmu gasped as pain went through her body. The source of her pain was her left arm, where Reimu had been holding onto her. Where Reimu had been grabbing her was a spell card that the shrine maiden had concealed in her palm.
Youmu's eyes widened as she realized what Reimu was about to do.
"No, wait!" But it was too late. Reimu grinned and then activated her spell.
"Duplex Danmaku Bounded Field!"

Marisa sat in a chair in the middle of a large room. The paneling for some of the walls was green, and others black, but the room stung the eyes with a main color of pure white. Marisa was glaring at a girl standing far above her behind a podium. This girl was the Yama, or judge of the dead, Shikieiki Yamaxanadu.
"Okay, I know this is court and all, but why'd you have to go and tie me up?" Marisa said, kicking her legs in retort. Marisa's hands were tied behind her on the chair and she had no way of getting free.
"Because you are a loose cannon, Marisa Kirisame!"
"Not unlike your mouth…" Marisa said under her breath, giving up her angry kicking.
"What was that?" The Yama said.
"Oh, nothing…"
"Well, whatever. I have watched you for many years, Mrs. Kirisame, and I believe that you are one of the most disgusting denizens of Gensokyo. You've stolen goods from countless residents and you always blow up everything in your path without a second thought! I hereby banish you to one-hundred thousand years in hell!"
"What the heck?" Marisa said, with her mouth gaping open in astonishment. "You can't just do that! I thought this was supposed to be court!"
"You dare object?" The Yama said, looking down on the girl with an evil grin.
Marisa opened her mouth and then looked at herself. She was tied to a chair. Not really a great situation.
"So…uh…how long was that again?"
"ONE HUNDRED THOUSAND YEARS!" The Yama screamed. She quite enjoyed that number, and she swished her baton in the air with joy to show it. A portal to hell opened up in the floor and Marisa could hear screaming coming from the open gape.
Suddenly, a blue flash came bursting forth from the open hole.
"What?" The Yama exclaimed as the blue flash revealed itself to the room.
"TA-DA! THE STRONGEST HAS ARRIVED!"
The Yama put her hands to the sides of her head in agony. "THAT IS IT! I'VE HAD IT WITH BOTH OF YOU! I BANISH YOU BOTH TO HAKUGYOKUROU…LET YUKUKO DEAL WITH THIS CRAP!"
She swished her baton in fury, and the fairy and witch found themselves standing on a small mountain several yards away from a giant tree that seemed to reach to the night sky above them. Or at least, they would have been standing…but Marisa found herself still tied to the chair.
"Dammit, she couldn't have at least untied me?" The witch struggled, trying to get free from her constraints. Cirno watched the witch struggle for a bit before floating over and looking Marisa dead in the eyes.
"…Where are we?"
"I have no idea, why don't you get me untied first?" Marisa glared at the fairy.
The fairy fluttered over to the ropes tying Marisa's hands and tilted her head in confusion.
"What's taking you so long? Just untie me!" Marisa yelled, kicking her legs in annoyance.
"How?"
"What do you MEAN how?"
"I don't know how…"
"Just pull on one of the ro-" But as Marisa said this, she felt a hard tugging on her hands and yelled out in pain.
"Ow! Not THAT rope! The other rope!" Marisa felt a small tug, and her hands were free.
Marisa jumped out of the chair and rushed over to the fairy, tackling her into a hug.
"Get off me! I'm the strongest you know! I'll have your head for this!"
"Oh, Cirno, I thought you were done for…"
"Well, I was for a moment there, but that mean lady opened up the hole and I could feel a gust of cold air so I latched onto it! Only a genius like me could have come up with such a feat."
Marisa untangled herself from Cirno and stood up, observing her surroundings.
"Well, now that we're both safe…where are we?" They were standing on the side of a small mountain ledge that curved around the peak and led off onto a small dirt road. Ahead of the road was a small garden. Marisa squinted and could make out two shapes, one of which was familiar to her.
"Hey, that's Re-" But just as she was about to finish her sentence, a sonic boom shattered her words, sending ripples of force through the air around them.
