Disclaimer, I do not own Danmachi or Pokemon

Bell gulped uneasily as he looked at the mirror. The costume store was out of any of the good costumes. All they had left for him was a hair band that sported white bunny ears. He wore his bunny ears and looked embarrassed as his appearance. He put his Hestia Knife in his back waist sheath. Looking at the back pack he saw that there were several safari balls.

Bell walked out the clothing changing room he saw Aiz waiting for him. She wore a pink dress with a tiara. Her sword was on her belt and a pink purse with safari balls was on her person. Her back bored a pair of false wings on her back.

Bell looked at her and said looking down with a blush, "Aiz, you look good."

Aiz smiled faintly as she replied to him, "Thank you."

Lilly walked up dressed with a fox hood. A fox tail was worn on the back of her belt resting on the back of her blue kimono. The black belt or obi matched the ears and tail in coloring. Most Kimonos did not come with hoods, but this costume did. The costume made her look like a kitsune. She bore on her back a large backpack full of safari balls and equipment for dungeon crawling.

Lilly looked up at Bell as she asked cutely, "Do I look good, Mr. Bell?"

Bell nodded as his face became redder, "Yes, you do Lilly."

Aiz smiled as she said to them, "Alright, let's go. This is the only night when ghost, dragon, dark, physic and fairy type pokemon come out in force. And they won't approach you unless if you are dressed in costume."

Bell, Aiz and Lilly walked into the mouth of the dungeon.

First Floor of the Dungeon on Halloween Night

As Lilly walked her mind was focusing on why Bell had insisted on asking Aiz to go into the dungeon with them on Hallow's Eve. Her foot stepped onto a small blanket of sand as she began to be swept into the air with a scream, "WAH!"

Bell dashed with his Hestia Knife as he glared slashing at the Sandygast's sand. The young girl landed on her backpack as a few safari balls popped out. One struck the Sandygast. The ball opened to try and seal the pokemon inside it. But, the pokemon was still far too strong, shattering the ball. The pieces fell to the ground as Lilly rolled to her feet.

Bell landed as the dungeon growled its command, Bulldoze. The pokemon's sand drove forward and rammed into Bell's vambrace. Slamming his knife into the sand he struck the ghost type pokemon with the magic of his knife. Pushing it back he leapped back and threw out his pokeball. Popping out was CaterpieCamm.

The green bug pokemon formed a pair of green mana fangs. Bell threw his arm forward shouting, "Bug Bite!"

The magic fangs bit into the body of sand that made up Sandygast's body. Bell pulled back as he shouted throwing up a red jewel, "Firebolt!"

From the jewel came the magic that Bell had learned just a week ago. The fire struck the pokemon as Lilly threw the safari ball at it. The ball hit it after the firebolt inflicted its damage. The pokemon had a seal appear under it and capture it inside. The ball stopped humming and quieted.
