Hey! Here's a new story that relates to Agito!

I do not own Persona 3 or Kamen Rider Agito

Kamen Rider Agito: Hour of Light and Darkness

Minato Arisato was a tiny bit surprised when his new friend Yukari Takeba took him up to the rooftop just to see a monster that she calls a Shadow. Minato now knew why Yukari brought out a gun, but he thought she was gonna shoot the Shadow not aim it against her forehead.

Right now, he dosen't know what to do since Yukari was knocked away dropping the gun.

"Go on." a voice said as Minato saw the kid he met on the first day here in his mindscape.

"There!" Akihiko Sanada said as he saw Minato on the secruity camera with Mitsuru Kirijo and Shinji Ikutsuki. The two seniors got up from the chairs to help them but...

"Wait." Shuji said surprising the two, as for him he looks anxious to see something.

Minato picked up the gun and examined it a bit before he pointed it at his head, remembering what Yukari was trying to do, which made him think it wasn't meant to kill, as he pointed it at his head one word came into his mind. "Persona." Minato said as he pulled the trigger, instead of killing him, the sound of glass breaking and a blue aura surrounded him and the blue aura started to forge something.

Thou art I... and I am thou.

From the sea of thy soul I cometh

I am Orpheus, master of strings.

The blue aura created the 'Persona' which looks like a humanoid machine doll with a silver metal harp on it's back. This is Orpheus.

Orpheus did a roar as it echoed around the area while Minato did a smirk in an almost evil way, the blue haired boy then suddenly felt pain in his head while inside of Orpheus, the inside of him glowed red and he started to litterally crack as he then broke making a new Persona take his place.

It's a giant humanoid that has a white head, wearing a black robe with white legs and white arme and around his are coffins attachted to it by chains. This is Thanatos.

Thanatos roared as it drew out a sword while Minato was gasping in exhaustion, Thanatos then jumped towards the Shadow as it started mercilessly beating and killing it, it then chopped the Shadow's arm off making black blood spill out of it, Thanatos then sliced it's mask like face off and it landed on the ground before the Shadow's remains disappeared.

Thanatos then breathed in and out before it squished a remaining arm then did a loud roar before Orpheus took it's place. Orpheus floted over Minato for a bit before it disappeared.

"Is it over?" Yukari muttered softly while her voice was shaking a bit, she and Minato heared the sound of footsteps and looked to see a humanoid leopard like creatures. "What are they!? she exclaimed seeing as they aren't Shadows.

"Wow, even in this situation they just don't give up." Minato said as Yukari looked at him on what he meant. Minato then did a hand movement as a vortex of light appeared on his waist before materializing into a belt, which surprised Yukari a bit.

Minato extended his hand slowly.

"Henshin!"

He then pressed the two large buttons by the sides at the same time and he shined brightly, one of the monsters was about to attack but Minato punched it back, the Leopard Unknown stumbled before attacking again but Minato blocked it and kicked him away. The light soon faded away revealing an armored warrior.

He had a black body suit and golden armor around his chest, wrists, and ankles. His mask also had a golden piece in the middle separating his eyes and the silver mouth piece. The belt around his waist was red, black, and gold with a large button on each side.

This was Kamen Rider Agito Ground Form.

"Agito!" the Leopard Unknown wearing a blue scarf exclaimed.

"Agito?" questioned Yukari as this one was new to her.

"I'll explain this later." Agito said. "Right now before we fight, I would like to know my opponents names."

"Very well." the white scarf Leopard Unknown said. "I am Pantheras Tristis."

"I am Pantheras Albus." the blue Leopard now Albus said.

"Close enough." Agito said as Tristis charged at him, Agito then dodged a punch before he punched it in the chest, the two exchanged punches until Agito kicked him in the chest before a light vortex appeared above Tristis's head, it reached up and drew out a spear.

"So you want a spear fight huh?" Agito said as it tried striking Agito with its spear but Agito blocked it before pressing the left button on his belt. Soon something came out of the center of the belt and Agito pulled it out, revealing a blue twin-bladed staff. Agito quickly turned around before slashing it with the staff.

Albus fell on its stomach before Agito stomped on its back, it tried to get up but Agito was forcing him down, as Agito was holding his staff, a swirl of light consumed him and when it faded, he looked different. His left arm turned blue along with his chest piece and the center of his belt turned blue, his staff's blades extended as he twirled it around.

"He changed!" Yukari exclaimed as Albus found the opertunity to kill her so it took out a bow and arrow then pointed at her, Agito looked at her noticed what going on.

"Watch out!" Agito said as he ran towards Yukari, who noticed Albus poinying the arrow at her, and blocked the arrow coming at her, it striked him in the chest making some sparks come off him. "Hurry and run!"

"But I can't..." Yukari started.

"Do you want to die!?" Agito said as he block a slash from Tristis with the Storm Halberd and slashed it a few feet away giving Yukari the time to run, Agito then stood up stood up and charged at it, then slashed it a couple more times making it back off a few meters.

(Play Kamen Rider Agito - Believe Yourself)

Agito then started twirling his staff around making it build up wind. Tristis was about to charge but he couldn't, the wind was stopping him. After a few seconds, Agito charged and slashed the Unknown a few times before finishing him by slashing him across the waist.

Tristis stumbled back and groaned in pain before its light appeared over his head and after a few seconds, the monster exploded.

Agito looked to see the other Unknown, Albus charging at him

Agito blocked its attack before punching it in the gut, making it fly across the floor. As it landed and got up, Agito reverted back to his default form before his helmet unfolded crest horns next to the bigger ones.

Agito started to pose in a martial arts form as his symbol of yellow energy appeared at his feet. Yukari watched in curiosity from the window as the energy was absorbed into Agito's legs. Albus charged before Agito jumped in the air, he aimed in a side kick position before hitting the Unknown in its chest.

It flew back, as Agito slowly turned away in his pose. When he was facing the Yukari, the Unkown soon exploded. Agito got out of the pose as his helmet returned to normal.

(End Song)

Agito then got surrounded by light which reverted him back to Minato, he then smirked as he collapsed.

Yukari gasped as she opened the door and rushed to his side.

"Are you okay!?" she exclaimed as she was shaking him a bit. "Come on, say something!"

A man dressed in all black watched the battle between Agito and the two Unknown as he was also thinking about the Shadow.

"These 'Shadows' are a threat to humans, I shall eliminate them along with those that have the potential to be Agito." he said as he now walked away from the scene.

Done! This is my first story that will involve a game, icluding Persona. Oh and before I go here's this small spoiler... Minato will not die or become the seal. Goodnight!
