It was on All Hallows' Eve, Geiz is not really for All Hallows' Eve at all. He has bad memories of that holiday. Kaylee saw Geiz is in a bad mood and has been hiding in the bedroom from everyone. She wondered what caused him to be in that mood. Her daughter, Mirai, snuck into Geiz's room and see him hiding under the bed.

"Dad, why are you hiding?" Mirai asked.

"I am not telling you," Geiz said.

"Please, I want to know," Mirai begs her father.

"Nu-uh," Geiz said.

Mirai doesn't like it when her father doesn't tell her. She knew that it had to be something with the holiday but couldn't figure it out. Mirai left the bedroom and went to see her mother. Mirai sees Kaylee writing a story in the living room.

"Mom," Mirai said.

"Huh?" Kaylee said as she looked up to see her daughter, "Oh hey Mirai. Need something?"

"Yeah. Do you know anything about why Dad is hiding?" Mirai asked.

"Hmm, now you mention why he is hiding. It's the time of the year where he normally hides from the world," Kaylee said as she put the pencil down.

"What do you mean-Oh you mean that he is afraid of All Hallow's Eve?" Mirai said.

"Yes. One more thing he is deadly afraid is the ghosts," Kaylee said.

"NANI?!" Mirai exclaimed.

"Yep. Found out long before you were born when your uncle, Woz, and Tsukuyomi did the pranks on Geiz. No, I was not involved in it. I found out from Tsukuyomi when she told me because I was out that day," Kaylee said.

Mirai got some devil face on her face as she got an idea. Kaylee saw and felt bad for Geiz if he ever got into the pranks by their daughter. Kaylee watches Mirai left the room.

"Mirai, I hope you are not planning to prank your father so badly," Kaylee murmured to herself.

Mirai went to her room and make a plan to scare her father. She was hoping that he got over the fear of the ghosts or otherwise he would not be able to get out of his room due to being afraid of the ghosts. Mirai was thinking that she should dress up as the ghost and makes her room very haunted. Mirai pulls the outfits out of her closet to see which one she will wear. She found at least two outfits and layout on her bed.

"Let see which outfit would it be best to wear?" Mirai murmured to herself.

Mirai looked at between two outfits. Geiz sneaking out of his room and went out for a walk. Mirai heard someone went out so she walked to the window and see Geiz outside.

"Guess I need to change my room into a haunted room before Dad comes back," Mirai murmured to herself.

Mirai went to work on her room after putting two outfits hanging in the bathroom so she can change later after thinking about which outfit she wanted to wear. Mirai went to pack all of her books and clothes into the boxes and take it to the attic until she is done with her plan. Kaylee was asked by her daughter to see if she can help Mirai taking some of the boxes into the attic. Kaylee agreed and help Mirai carrying the boxes into the attic.

"Thanks, Mom for helping me," Mirai said.

"Your welcome sweetie but what are you planning?" Kaylee asked.

"I can't tell you but it does involve with Dad," Mirai said.

"Wait a minute! Are you pranking Geiz?" Kaylee asked.

All Kaylee got the answer from Mirai's grinning face and knew it was true. Kaylee shakes her head and smiled softly.

"Just don't scare your father badly," Kaylee said.

"I won't Mom," Mirai said, "Can you help me with the room please?"

"Sure. What do you need help with?" Kaylee replied.

Mirai took the phone out of her pocket and pulled the album from her phone. She showed the picture to her mother.

"That is really creepy," Kaylee commented.

"Yep. This will be perfect in my room to scare Dad," Mirai said.

Kaylee nodded as she smiled at her daughter. Mirai smiled back. They went to work on Mirai's room for several hours.

A few hours later, Mirai and Kaylee step back to look at the room. They were proud of their work. Kaylee knew that Geiz would freak out if he ever finds out that Mirai's room has changed. They also put the camera in the bedroom and the entrance of the bedroom to record everything.

"Thanks, Mom for helping me," Mirai said.

"Your welcome sweetie," Kaylee said, "Is there anything else you need?"

"Actually yes. Can you help me which outfit should I wear to scare Dad?" Mirai asked.

"Sure," Kaylee said.

Mirai and Kaylee went back into the bedroom. Mirai went to the bathroom to bring two different outfits to show it to her mother. Kaylee waited for her daughter to come back. She was thinking about how Geiz got scared and pass out many years ago. Kaylee chuckled to herself. Mirai carried two outfits and show it to Kaylee. Kaylee looked at it and picked one.

"This one. I believe it will scare your father," Kaylee said.

"Ok Mom," Mirai said.

Mirai went to the bathroom and change into the outfit that Kaylee helped her. Kaylee waited and standing by the window to watch for Geiz to come back. Kaylee doesn't see Geiz so that means he is still not back yet. Mirai walked out of the bathroom wearing the outfit.

"That is really scary," Kaylee said.

"Thanks, Mom," Mirai said.

"Welcome," Kaylee said, "I will have to leave and your father is not back yet."

"Ok Mom," Mirai said.

Kaylee smiled and leave the bedroom which is now a haunted bedroom. Mirai walks to the window and stands outside to watch for her father to return. She watched out the window to find Geiz and wonder when he will come back. Geiz walking back to the house and saw something strange at Mirai's window. He thought he saw someone standing at the window but shakes his head when the person vanished from the window.

"Weird," Geiz murmured as he entered the house.

Mirai saw her father came back and left the window to hide from him. She is ready to scare Geiz. Geiz walked in and went up the stairs. He stopped at the top of the stairs and heard a strange sound.

"W-what was that?!" Geiz said.

Mirai heard him and smirked as she keeps making strange sounds. Geiz starting to get scared and followed the sound. He stops in front of Mirai's room.

"Why is her room has strange sounds?" Geiz asked to himself.

As soon he spoke it, the door opens by itself. That startled Geiz and slowly walked into the haunted bedroom.

"H-hello? M-Mirai?" Geiz asked.

The door shuts behind him. Geiz jumped high and turn around to try to get the door open. The door is locked and he can't get out. So, he turned around slowly to see the room different. Geiz got so scared and hoping there is no ghost nearby. Mirai smirked and makes a strange sound again.

"W-who is there?" Geiz asked.

Geiz saw Mirai or rather the ghost of Mirai. He is really freaking out and trying to get out of the room. Mirai slowly walks toward Geiz.

"N-No get away from me?!" Geiz screamed.

"Daaaddddyyyy," Mirai moaned.

Geiz screamed loudly. Mirai touches Geiz's shoulder. Geiz freeze up at the touch and fainted. Mirai looked at her fainted father and shakes her head.

"Guess he's still afraid of ghosts," Mirai said.

Mirai looked up at the camera and smiled. Kaylee watched outside of the room. Kaylee smiled knowing it is true. Kaylee stops the recording and went to Mirai's room. Kaylee walked in and sit on the bed with Mirai. The girls waited for Geiz to wake up which he did in ten minutes after he fainted.

"Ow," Geiz murmured before looked up to see Kaylee and Mirai.

"Hey, Geiz. Looks like you are still afraid of ghosts," Kaylee said.

"Yeah..." Geiz replied.

"Happy Halloween Dad," Mirai said.

"You did that?" Geiz asked.

"Yep. With the help from Mom to decorate the room," Mirai said.

Geiz looked at Kaylee. Kaylee nodded that she did help Mirai. Geiz sighed and gets up. He gave the hug to Kaylee and Mirai.

"I love you both," Geiz said, "You did scare me badly."

"We love you too," Kaylee and Mirai said.

"Sorry Daddy," Mirai said.

Soon after that prank, Geiz seems warm-up to Halloween but still afraid of the ghosts. He knew that his wife and daughter will be there for him every year since that year.

I don't own Kamen Rider Zi-O but I do own my ocs: Kaylee and Mirai. Happy Halloween!
