You wanna know why?! (Samuru Shigami x O.C)

You're lying

Gensouke sighed knowing that Samuru found the secret player of the WBMA.He was about to explain when...
"No. You're lying" Samuru said firmly
"What??" Roii asked
"Drop the act. I know Roii is still in her home, so shut up and drop act" Samuru said raising his voice a bit.
"But I'm not!!" Roii said protesting.
'How could you think I'm lying? Does this mean I wasted my efforts trying to find you??' Roii thought.
"Shut it. You may have the dress but I gave her more than a dress!!" Samuru said almost shouting.
'Tch. This girl is persistent. I know Roii wont waste her time going here' Samuru thought.
"You gave her a shawl and a pair of slippers, aint I right?" Roii said balling her fists trying to hold back her anger.
"Well if you were Roii you wouldnt take off the shawl!" Samuru said
"Why do you think I sown these on the dress??" Roii said moving her hair slightly to show a button ,Samuru looked to her other shoulder to see another button.
Roii adjusted the belt of her kimono to show a small pouch, she opened the pouch and brought out an old looking shawl and buttoned it to her dress as if it was a cape. Roii smirked a bit
"Believe me now??" She said a bit of cockiness to her voice
'Haha!! Surely you'll believe me now' Roii thought internally laughing.
"No." Samuru said firmly, this broke Roii's heart to a thousand pieces. She slammed her fist to the coffe table making a scratch and grabbed Samuru's collar dragging him to the elevator.
"What the hell are you doing??!!" Samuru said clearly angry
Roii didnt respond and only pressed a button.
'Rooftop?? What is she doing??!!' Samuru thought. Roii released Samuru's collar and got her phone and texted someone.
After they arrived to the rooftop, they waited for a few minutes till a hellicopter arrived.
'That's the WBMA's hellicopter? What is she planning??'
Roii grabbed Samuru's collar again and dragged him inside forcing him to sit down. Samuru knowing she wont entertain any questions decided to give up and sit down quietly.
-time skip-
Roii once again dragged Samuru inside a building . Samuru recognized it as the main WBMA building.
'Thanks goodness no one but us inside' Samuru thought, well of course who'd want to be embarassed?
"What are we doing here??" Samuru asked, Roii smiled and looked at him.
"I'm going to show you a proof that can never be imitated, even in a million-bajillion years" Roii said grabbing her phone twirling it a bit and dialed a number.
"Yes.... Bring it on.... I'm not going to destroy anything..... Thanks" were a few words Samuru can understand due to Roii's fast talking skills. "Miss Roii, I'm here~~!!" Rory said showing a silver case with a label colored in red, white, blue, and yellow glitters and other decorative ornaments. Roii skipped to Rory and grabbed the case.
"Thank you Ms. Rory~~!" Roii said saluting. Rory giggled and went to the sidelines. Then a a rapid fire challenge showed up. Roii put on her earpieces and went to her place smiling brightly. She brought out her bdaman.
"Samuru, isnt that Dragnarok?" Dravice said
"Shut up. It might also be an imposter" Samuru said shushing Dravice
"Well excuse me." Dravice said apologizing.
"Ready..... Set....... CROSSFIRE!!!" Miss Rory shouted.
Immediately, the gauge on Roii's gloves went up. Roii gently tapped her gloves on the counter and metal attachements appeared. Samuru examined her gloves from a distance and recognized the Aquarius sign.
"Naval Battle" Dragnarok said
Samuru's eyes widened immediately.
'Only one b-daman can do that!!'
Roii smirked and adjusted her pose.
"Open gate of the Water Bearer... Aquarius!!!!!!!" Roii shouted
A queenly looking mermaid figure made of water appeared and brought a huge tsunami inside the arena.
After the water subsided, all that could be seen are the targets with holes in the middle and a few seaweeds here and there.
"Believe me now?" Roii said
Samuru couldnt find another reason why she was an imposter so it must be her.
Samuru hugged her tightly surprising her
"Yes, yes I do believe now" Samuru whispered at her ear
Roii happily hugged him back and buried her face on Samuru's chest.
She was happy to know Samuru recognize her now..
