Rena's POV

My head still hurts from the blow last night, and i opened my eyes slowly to see that Keiichi-kun was in front of me watching me wake up.

"Rena! she's regaining consciousness!" Keiichi-kun said, yelling to the unknown man next to him.

"You OK, little girl?" The man asked.

Actually there were 2 unknown men next to Keiichi-kun. One is wearing a white shirt, which is untucked and some of the buttons were unbuttoned, a blazer at his right shoulder, and also he wears black jeans with a silver chain inside it's right pocket. He has a short black hair and wearing sunglasses. I also noticed he is wearing a strange silver belt.

The other man is wearing the same attire as him, only much neater. There is a logo BHS on the blazer, and he wears a tie. He has a curly hair, and was carrying a guitar. He also wears the same belt, but with a black buckle.

"Urghh, what happened? Who are these guys Keiichi-kun?" I asked.

"These 2 people found you lying on the ground in front of my house." Keiichi-kun said, pointing to the 2 men, the sunglasses wearing man nodded, while the other just played the guitar.

"I'm Kizami Seiji, and that's Nohara Hiroshi, my best friend." The man wearing sunglasses said while pointing to the guitar player

"I-I'm Ryugū Rena, nice to meet you people." I said, introducing myself anxiously, before a painful feeling surged into my head.

"Do you remember anything Rena?" Keiichi-kun asked me.

"I remembered being hit by someone, before She glows in a purple light and shapeshifted into me." I said, making Seiji and Hiroshi surprised.

"A native attacked you, huh?" Seiji said.

"but that's impossible, i thought it would be instant death upon being attacked by a native." Hiroshi said, still shocked by my story.

"Well, she's lucky, idiot." Seiji said to Hiroshi

"Enough." I said to them, stopping the argument, then i stood up, and went for the front door, however, right when i opened it, i saw another demon, it's green in colour and has a face that looks like a human skull, it has a claw in the right arm and a hand with 5 fingers on the left arm.

"WHOA!" i screamed, before it hissed to me.

Suddenly a device which looked like a scorpion came to me, and i was handed a strange sword by Seiji.

"Insert that scorpion device onto the sword!" Hiroshi said

I then did what he said, and i unconsciously say "Henshin!" before the device also said Henshin, but with a semi robotic voice.

3rd person POV

Nano particles swarmed from the device to Rena, transforming her into Sasword. The demon then tried to charge at Rena, but was countered with a slash by her. The slash forced the demon to back off, before it starts moving strangely, and started to molt.

As the demon molted, it's previous green body was no more, it was replaced with a sword shaped claw on it's right arm, and it's left hand became a large shield.

Rena then unconsciously pushed the tail on the sasword device, and it gives out tachyon waves all over Rena's armor.

"Cast off!" Rena said, before the device repeated her words.

Then all of the sudden, the armor was blasted away from her body in high speed, sending the demon flying. Rena's visor then glow.

"Change,Scorpion!" The device said.

Rena then unconsciously said another word, "Rider slash!" before pulling the tail of the device, and pushing it back. The device later repeated her words and gives out a tachyon wave all over her sword.

Rena then ran to the demon, who is still midair in high speed and slashed it 4 times and was given a final slash, where her back turned after the slash, and the black liquid on the sword was pouring to the floor. The demon then exploded, meaning it's death.

"I'm going to kill all the demons here. That's my priority right now." Rena said, making her 3 friends smiling.

However suddenly pain came to her head out of nowhere, and she reverted back into human form.

Rena's POV

"Urgh! Ahh!" i yelled in pain, feeling the demon from last night's power. The pain was unimaginable that i have to hold my head with my hands.

"What's wrong?" Keiichi-kun asked, but i ignored him and walked away from his house, and to the river.

"I can feel it... i can feel it's power... She is... where!?" I said to myself before looking at the water in the river.

However it's not my reflection in the water, but it's that demon from last night.

3rd person POV

Rena then glowed in purple light, and as the light faded, she transformed into the demon that she saw last night, and began to growl.

"AAAAH!" an ear hurting scream came out of nowhere.

As the demon looked towards the source, she saw a little girl with blonde hair and a fang inside her mouth. The demon then walked toward her.

Satoko's POV

"What should i do to fight someone close to me?" I asked myself, holding the blue stag beetle device i got from Kizami-san.

A/N well, who do you think will win? Anyway, i hope you like this fic, Cya!
