*This chapter takes place during Oniland event.*

After fours years of being at Chaldea, Ryan has seen a lot of different Halloween events. For example, the first event was a festival, the second was felt a dungeon crawl through an retro video game, and last year was exploring three different castles in order to stop Osakabehime from using Elizabeth Bathory to create her ideal paradise. However, nothing prepared the brown haired boy fkr this year's Halloween event to be an Oni-themed amusement park....which was awesome! Ryan loved amusement parks and being here at Oniland was bringing back all of the memories his trips to amusement parks with his family.

"Which should we ride first?," the brown haired boy asked. "The roller coaster? The tea cups? Or maybe we can try some games? I'm really good at amusement park games."

"Umm....Master?," Ibaraki Douji stated. "You do remember that we are here to resolve a singularity here."

"Oh yeah...," the male master said with a frown as he remembered that Chaldea had detected a singularity that ended up being a singularity as the organization sent Ryan, Gudako, and Ibaraki Douji to resolve the singularity. "But we can ride the rides later right?"

"Yeah...I was looking forward to riding the Ferris Wheel and doi—," Gudako stated before getting smacked upside the head by Ibaraki.

"Get your head out of the gutter! We have work to do!," the Berserker class servant exclaimed.

"Ok......," the two masters of Chaldea stated with pouts on their faces as the oni was ruining their amusement park fantasies.

However, the group's immediately turned when some oni wearing name tags and uniforms came up to them wielding clubs. "Hey! Who let those humans in?! This is an oni amusement park only!"

"That's racist!," Gudako exclaimed. "You should be ashamed of yourselves!"

"Listen up, humans.," one of the oni guards said. "Take your kid and get out of here or we'll make you leave ourselves."

"Wait...you think we are a couple?," Ryan said as he pointed to Gudako and himself.

"Wait a minute! Who are you calling a kid?!," Ibaraki Douji exclaimed as she raised her weapons. "You are so dead!"

With that, the berserker class servant rushed into against the oni guards as the two masters heard a familiar voice said, "Actually, I think they are talking about me."

Ryan and Gudako turned to see Chloe von Einzbern standing behind them (I actually heavily relied on her during the event).  "What are you doing here?"

"I just wanted spend some time with you, Master.," the Archer class servant said. "Can I have some mana?"

"Maybe if you help Ibaraki with those guards, he'll may give some.," the orange haired girl said.

"Deal!," Chloe exclaimed as she drew her swords and joined in the battle.

Ryan immediately just turned and glared daggers at Gudako. "What?"

"Are you trying to send me to jail?," the boy asked as the battle raged on.

While Chloe and Ibaraki Douji were able to dispatch the first pair of guards, more just showed up to take their place which also included several large oni. It also seemed like the duo were barely doing any damage to the oni and the pair of masters were starting to run low on mana. If the group didn't do anything soon, they would be overrun. 

"So, what do you want to do?," Gudako asked. "Should we run?!"

"Give me a moment to think!," Ryan exclaimed as the oni got closer and closer.

"Well, you better think of something quick!," Chloe yelled as she slayed another oni.

"What are you guys talking about? I could do
this all day!," Ibaraki Douji yelled as she torched several guards. "I can do this all day!"

The masters just glared at the berserker class servant while the guards closed in. It seemed like all was lost..... that is until a shining light blasted down from nowhere killing several oni guards in an instant. The group from Chaldea looked on as standing where the light fell was a familiar looking oni that Ryan had first met during the Rashomon event and Ibaraki Douji's best friend: Shuten Douji...but she seemed different somehow.

"Magifender oni Shuten is here to save the day!," the Assassin(?) class servant said as she began effortlessly kill all the guards.

"Wow! Who is this strange oni?!," Ibaraki Douji asked.

Chloe raised an eyebrow at the berserker class servant. "Ummm...that's obviously Shuten Douji."

"I don't  think so.," Ibaraki said. "I know Shuten and I would think I would recognize her if I saw her."

"Obliviously not.," the Archer class servant said as she turned towards her master. "Master. Back me up h—"

Chloe von Einzbern jaw immediately dropped in disbelief as both Ryan and Gudako stared Shuten with lustful eyes. "So sexy...."

What is happening right now?!," the loli servant asked as Shuten finished off the last oni as she walked up to the group.

"You are safe now, citizens. Now I will take my payment.," the magifender oni said as she grabbed Ryan by his shirt collar and claimed his lips with her own.

"Lucky.....," Gudako said with a pout. "Why does he always get the attention from the sexy girls?"

After few minutes, Shuten let Ryan go as she began to fly off. "Until next time, citizens!"

"What just happened here?," Ibaraki Douji asked.

"I don't know....but she left me her phone number.," Ryan said as he held a small piece of paper.

"Can I have it?," Gudako asked.

The pair of masters immediately were pulled forward as Chloe dragged them away from the scene. "That's it. We're settling Thai singularity as soon as possible. There's only so much stupidity that I can handle."

With that, the group continued their adventure in Oniland  and once the singularity was resolved, Shuten Douji decided to join Chaldea....which immediately caused a war between her and Summer Raikou to begin, but that's a story for another time.
