A/N Heads up there will be limes, lemons, etc in this story just a minor heads up. There will be a lime in this chapter.

Relooking at the letter and the mission scroll for the fifth time this week. Sitting just outside my room, I growled while Seitaro questioned," Whats up? You still haven't told us what those are about."

Looking at my fiance and best friend I sighed," The letter is from the fucking leader of Oni no Kuni. Here let me read it: Keiji Namikaze

While we may be enemies I wish to see you grow as a Demon Slayer and prove yourself worthy of fighting me. Learn this breathing style and you will be one step closer to be a worthy adversary. You are now named the Kinoe Flame breathing demon slayer.'

Signed,' Kokyu Kibutsuji Leader of the Demons and Great Granddaughter of Muzan Kibutsuji.

Both their eyes were wide in shock while Saya whispered," Do you know what this means Keiji-kun?"

I spat," I have the most powerful demon after my head yes, yes I do."

Seitaro spoke cautiously," Judging from your anger I don't know if its wise to ask but what is the mission?"

I snarled while Killer Intent flared while both paled slightly while I calmed myself down slightly," Hokage-sama wants us to go to the fucking front lines and while you guys assist sensei, aniki, and kaa-san. I get to fight a demon stronger than anyone one I have ever fought!"

This time killer intent truly flooded out of me while my father came skidding out and nearly crashing into a pillar and the Hokage appeared in a shunshin while I fixed him with a death glare and he paled while Saya tugged on my arm while I brought the killer intent under control.

"Hokage-sama I accept the mission. I am not having anyone in harms way however. I go alone."

Immediately sounds of protest sounded while I stated," I am not putting you guys in danger, especially against a demon that is stronger than any Kage. I am the only one who has a shot in fucking hell who has a tiny chance of winning. You guys just started in breathing styles.

They both looked down while I breathed out," Good that is settled. Now Hokage-sama, I want your word for two maybe three things. The first I want you to help my sister with her mental issues from the rape experience. The second if I do not come back do not let them come after me."

He nodded while I looked at Saya and Seitaro," I'm sorry, yes I know we are a team but I will not let you guys go on the frontlines against a powerful demon such as that."

Seitaro breathed out," Fine, Taicho, just don't die."

I smirked softly," Not to worry. I am very hard to kill given the countless assassination attempts on me."

My father was silent and breathed out," Keiji, while I respect most of your decisions completely I really don't think going solo is the best idea."

I shook my head," Father, this is something that is too dangerous for my team. Yes all of us are Jounin level in shinobi combat wise, but I am the only one who is powerful enough with my breathing and kenjutsu skills to at least anticipate how they will attack and what demon art they have. Remember I have fought one with music, blood, and a shadow demon art. That and probably five dozen more They are not ready for that yet."

Saya groaned," When will we know we are ready?"

"When you can scratch me with your blades. Which you both are no where near ready yet."

Seitaro sighed," Damn you."

"Why for watching out for you guys? Either way Hokage-sama I will be leaving tomorrow afternoon."

He nodded," Of course I wish you luck for your mission. I will honor your requests."

Bowing slightly," Thank you sir."

I breathed out while he disappeared in a body flicker and I looked at my father," I'm sorry father, but this is something that I can't risk anyones lives over such a powerful demon."

Breathing out I laid on a tree just outside of my room while the cool night breeze when Saya's voice came from beneath me," Keiji-kun?"

"Whats up?"

Jumping down behind her she jumped startled while I noticed she was wearing a night gown and it revealed her body perfectly. Blushing furiously I turned my head while she spoke," Keiji, can we go into your room first?"

"Sure."

Opening the door I closed it behind us while I breathed out forming hand seals and activated a set of seals, a privacy, a noise cancellation, and safety seals.

She whispered," Why?"

I walked over to her and gently lifted her chin," Because I want you safe. You are far too important to me. Plus I can trust you more than anyone, my love."

Lime Warning

Kissing her on the cheek while she blushed softly before kissing me back on the lips while she knocked me over onto my bed with a barely audible sound while we remained kissing before I nibbled on her lower lip as she opened it while tongues moved into the fray. She moaned while we pulled away while my hormones took over while I leaned forward while my mouth caught hers while we immediately went back to engaging in our tongues. She moaned while my hands reached up while I grabbed her breasts while she moaned while I pulled back with a gasp of air while she moved backwards and I quickly apologized," Sorry Saya-hime."

She shook her head, her face red slightly while she responded with a stutter," N-no worries Keiji. I-it was bound to happen."

(End of Lime)

We kissed one last time while she disappeared in a shunshin while I smiled lightly,' I promise Saya-hime I will protect you and come back to you soon.'
