Random thought I got when I was reading other Kamen Rider Fan fics. I don't own Kamen Rider Gaim or Danmachi (Is It Wrong to Try to Pick Up Girls in a Dungeon?) they are owned by there respective company/authors
Fallow the story of a young adventure...
Hestia: "I can't wait!" Hestia jumps off the bed and lands next to the closet. She opens up the closet.
Hestia: "Bell, I'll see you at six o' clock this evening in Southwest Main, at Amour Square!" Hestia grabs some clothes and leaves the church.
Bell: "Where is she going?"
Y/N: "Probably the gods bath house."
Bell: "Gods bath house?"
Y/N: "It's exactly how it sounds. Well enjoy your day Im going to the dungeon."
Bell: "Eh? You're not coming!?"
Y/N: "Of course not, you only invited Hestia remember?" Y/N smirks at Bell and walks up the stairs.
Bell: "You're right! It was supposed be all three of us! Senpai wait! Senpai!" Y/N stabs a Kobold through the chest for it to disappear. Y/N sheathes his sword then kneels down and starts to pick up the magic stones.
Y/N: "I don't understand what's going on...where are you Kouta-sama?" Y/N takes out his moldy lockseed to look at it.
Voice: "So you're the new Gaim." Y/N quickly stands up and turns around to see a white creature.

Y/N: "What the!?"
Creature: "My name is Grinsha, a Overlord." Y/N takes out his Sengoku Driver.
Grinsha: "I never met the first Gaim but that does not matter." Grinsha points his sword at Y/N. Y/N puts the driver on his waists and takes out his Pine lockseed.
Grinsha: "I'll be taking your life here and now." Grinsha runs at Y/N swinging his sword at him. Y/N dodges out of the way and pushes the button on the Pine lockseed.
Pine!
A crack opens for a giant pineapple to float out of it. Y/N slots the lockseed in his driver and locks it.
Lock on!
Y/N grabs the small sword and pushes it down to cut the lockseed.
Soiya! Pine Arms! Funsai destroy!
Y/N stands up as the giant pineapple floats on his shoulders unfolding into his armor. Grinsha swings his sword at Y/N as the pineapple unfolds. Grinsha's sword hits Y/N before it come finish unfolding making him fall to the ground. Y/N rolls on the ground then gets on his knees. He summons the Pine Iron and throws it at Grinsha. Grinsha hits the Pine Iron away and runs at Y/N. Y/N stands up and pulls on the chain of the Pine Iron. The metal pineapple flies at Grinsha hitting him in the back. Grinsha stumbles forward for Y/N to slash Grinsha with his Musou Saber. Grinsha staggers back from Y/N's attack.
Grinsha: "Arh!" Y/N spins his Pine Iron ready to hit Grinsha. An angered Grinsha runs at Y/N shoulder tackling him and pushing him back. Then Grinsha hits Y/N with his sword. Grinsha continues his angry assault slashing at Y/N. With one final hit Y/N is sent towards to ground making him de-henshin. Grinsha kicks Y/N making him hit the wall of the dungeon. The Overlord walks up to Y/N.
