"This way, inside of this very dungeon behind the waterfall lies a Mythical Beast named Asena. Many have come here to try and tame this beast, but those who enter never come back out. You think you are ready for this?" Tsuna looked at me as we walked behind the waterfall.
"Can't say I am since this is the first time I'm fighting a Mythical Beast, but I know with Arcane by my side..I can easily tame this Mythical Beast." I said.
Tsuna smiled and looked ahead. "This is my first time here. Rivule told me about this Mythical Beast. It is said that they mythical beast is female which isn't rare since many mythical beasts have genders. Now Legendary Beasts are different as most of all Legendary Beasts do not have genders at all except for a select few like Rivule and Pyroc. That aside let's get started on this quest."
I nodded and we both walked into the dungeon together and followed the path to Asena. I looked around and glided my hand against the wall of the dungeon. The wall was exceptionally smoother than most walls and very cold on top of that. As we walked together I sensed Rayne then dodged his attack. Rayne appeared in front of us then smirked as more of his forces appeared behind him.
"Well since I can't grab my hands on Rivule or the queen, I'll just kill you and take Asena for myself!" Rayne said.
"You again. I guess we've got to kick your ass once again." I smirked then summoned my sword and the Crest of Arcane shined on my hand.
"Let's show him our teamwork, my love. He's about the get the old Yeshan beatdown." Tsuna smirked.
I chuckled and looked at Rayne. "You're finished before this battle even...started."
I appeared in front of Rayne then punched his face. He groaned then was blown away. His forces dashed to me and Tsuna then we began to strike all of them down together.
"Azure Cross!" We both bellowed then I slashed down vertically and Tsuna slashed horizontally and we generated a cross shaped cutting wave that struck down the remaining forces.
I chuckled and dashed to forward and Tsuna formed into a puddle then rushed after me. I jumped up and landed on the puddle and I began to surf on Tsuna. Rayne looked at me then glared. He summoned his sword then slashed at me. We clashed and Tsuna moved accordingly to help me avoid Rayne's attacks. Rayne and I continued to clash then our blades clashed one final time before I jumped off Tsuna and she emerged from the puddle then punched Rayne away. He groaned and I appeared behind him then kicked him back to Tsuna. She grabbed his leg and spun around then tossed him in the air. I appeared above Rayne then kicked him down and he crashed through the ground. Tsuna and I followed him and jumped down the hole.
"Take this!" Rayne bellowed and punched my cheek then sent me crashing through a cave pillar.
I groaned then recovered quickly and landed on my feet. I wiped my mouth and smirked. I dashed to Rayne and dodged his attack then punched his stomach and he groaned. He coughed a bit then stumbled back. I kicked him away and looked at Tsuna.
"Let's do this." Tsuna smiled.
I nodded then she ran forward and I followed behind. I spun around and she made her body into water then I slashed in a circle and my sword's aura worked as an extended blade and my attack phased through Tsuna then hit Rayne. I bellowed and sent him flying into the air. Tsuna reformed above him and kicked him down. I slashed in a circle again and hit him a second time the jumped up. He groaned loudly as he was sent flying in the air once more. Tsuna bellowed and blasted him to the ground with a beam of water. I slashed down and struck him with my sword. He groaned and Tsuna appeared behind me then I jumped backwards.
Rayne panted and slowly got up. He bellowed and his aura surged powerfully. He tapped into his Awakened State then his Crest shined on his forehead. He vanished then appeared in front of Tsuna then punched her face, blowing her away. She groaned as she hit the cave wall and he appeared in front of her and kicked her away. He landed on the ground then looked back at me.
"Hmph.." I glared then dashed to Rayne then slashed at him multiple times, but he dodged each slash then palmed my stomach and I groaned then he punched my face and blew me away through a large boulder.
I grunted as I laid on the ground with the boulder pieces on me. I slowly got up and my hair covered my eyes. I moved my hair from my eyes then the Crest of Arcane shined brightly.
"Arcane!" I bellowed and my aura surged powerfully and turned golden. An aura crown appeared on the top of my head and I tapped into my Emperor's Form.
"Rivule!" Tsuna bellowed and a roar sounded then Rivule appeared out of the body of water beside us.
"Let's show him...our true teamwork." I said then smirked.
"Yeah.." Tsuna smirked and summoned her lance.
Rivule roared and empowered us. I dashed to Rayne and Tsuna dashed to him as well. My sword turned into its Yeshan Form and I slashed downward. Rayne blocked, but his guard was immediately broken. I vanished then Tsuna appeared in front of Rayne then kicked him away. I appeared in front of Rayne once again then slashed through him and he groaned as he was sent flying in the air.
"Tsuna!" I said then tossed my sword in the air.
Tsuna caught my sword then slashed down and send Rayne crashing to the ground then threw my sword at him. I appeared where my sword was then caught it then copied Tsuna's technique, making my body into water. Tsuna threw her lance at Rayne and phased through my body then the blade struck Rayne's. He groaned loudly as the blade went through his stomach. I landed on the ground and picked up the lance with Rayne still on it. I bellowed and slammed him to the ground then tossed the lance in the air.
"Let's end this!" I said.
"Right!" Tsuna nodded.
"Dual Ultima Arts!" We both yelled and out aura shined.
We dashed to Rayne as he slowly stood up. I spun around and used my Supreme Emperor's Impact on him and sent him flying then Tsuna used her Pure Heavenly Rainfall to strike Rayne back to the ground.
"Yeshan Glory!" We both bellowed and slashed down together a massive cutting wave sliced him in half and a massive explosion happened.
Rivule roared and went back into the water then the smoke cleared and all that remained was Rayne's Crest floating in the air. I held my hand out and absorbed the Crest and closed my eyes.
"He knows something about Alastor. I can use the Crest Reader and then give this Crest to Nebula." I said then opened my eyes and turned normal.
Tsuna smiled and nodded. "It's been so long since we used Yeshan Glory...My heart was racing the entire time."
"We still got it.." I smiled and pat her cheek then walked forward.
She blushed and watched me then shook her head and followed me.
We continued down a path to Asena. We began to hear singing and I was beginning to be hypnotized then my Crest shined and I broke out. Tsuna looked at me then looked ahead.
"A Siren's Song. Good thing Arcane is with you or else you would've been hypnotized by her singing." Tsuna said then walked ahead.
"So our Mythical friend is a Siren. I see.." I walked behind her then we entered am area, seeing a beautiful mermaid sitting in the middle of a body of water on a rocky surface.
"In time's flow, come the waves of the black sea. Listen to my voice and soon you'll fine protection and be free." Asena sang.
"I find that hard to believe." I said then stopped and looked at Asena.
Asena stopped singing and smiled then opened her eyes. "I see, you're the first man to resist my song. I am impressed."
I looked closely at Asena. She had long flowing sapphire colored hair, her eyes shined a light blue color and she had seaweed covering the nipples of her breasts and her bottom half was a scaly purple. She swayed her tail as she looked at me.
"You've come to obtain my Crest and make use of my Siren's Song?" Asena asked.
"That is my plan." I said.
"Well, I can not just give it to you. Prove to me that you are worthy of my power..." Asena said then summoned her trident.
I looked at her then felt her tremendously powerful aura. I grunted and guarded my face from the high winds her aura produced.
"Nngh! Her strength is too great, but I have an idea! She doesn't have very high defenses based on what Rivule said about her. With enough power, she can go down in one hit!" Tsuna said then slid back a bit.
"I've got just the thing!" I said then got in the Yascean Stance and my sword turned into its Willbreaker Form. "I don't have enough energy to go for any of my ultimate attacks...but I do have enough for one Sword Arts...With this stance and Willbreaker's Absolute Attack capabilities, a one hit KO is guaranteed. I just need more power!"
"On it! Rivule!" Tsuna yelled and Rivule appeared from the body of water where Asena was then roared and empowered me.
Asena yelled and multiple water arrows appeared behind her. She sent them all at me and I dashed towards Asena dodging all of her arrows. Tsuna held her hand out and formed a barrier around me, causing the water arrows to be absorbed by the barrier. I jumped towards Asena and bellowed.
"Sword Arts: Willbreaker!" I yelled then slashed through Asena and an explosion happened.
Asena groaned loudly and her aura disappeared. She placed her hand on the surface she was sitting on then panted. "Boosted by a Legendary Beast's power and a Royal Stance and Willbreaker...and I couldn't block it. It took all of my energy...I am impressed.."
I chuckled then grunted and fell on one knee, very fatigued. I panted softly and my sword vanished. My aura disappeared as well. "Heh...if I didn't know any of those stances or sword forms...I would've been in great danger."
"Yeah you would...I suppose you've earned my Crest." Asena smiled and held her hand out to me.
I looked at my Crest of Arcane then noticed the Crest of Asena shining on top of it and fused with my Crest. I was given the ability to use the Siren's Song. I stood up and smiled. "Thank you...Asena."
"Until we meet again. You can summon me anytime you please." Asena jumped in the water and disappeared.
I sighed and smiled. "This was tiring. I am in no energy to walk anymore."
Rivule roared and teleported us back to the castle then appeared on Tsuna's should in her companion form.
"Now that's a successful taming process. You've got Siren's Song, stated to be one of the best powers in Uthea. You're pretty stacked now." Tsuna smiled.
"I wish I could see it that way, but it's gonna take more than a song and dance to beat Alastor." I said.
"I know. Come let's rest in our room. I'm actually sleepy." Tsuna smiled and walked ahead.
"Sounds like a plan." I said then followed her.
