Alcruz gets a daughter, she will be revealed in later chapters, like two or three later.

Rinkah

"Rinkah."

"Hello Alcruz."

"Could I trouble you for some sparring?"

"Sure. Armed or unarmed?"

"You choose."

"Armed, then."

...

"You.. Are a... demon."

"I believe I win."

"Gahhh..."

"Good fight, Rinkah, I believe I know what to improve on."

"You can improve?"

Alcruz and Rinkah have reached C-Support

"Rinkah."

"Hey Alcruz, come to spar again?"

"If you want."

"Sure. Unarmed, this time."

"Very well."

...

"Rrgh!"

"Hah!"

"AHHH!"

"Ah! Rinkah, I'm sorry, I didn't mean-"

"You groped me you-"

"I swear, I didn't mean -"

"Out! Get out!'

"Rinkah-"

"OUT!"

Alcruz and Rinkah have reached B-Support?

"Alcruz!"

"Uh, Rinkah-"

'I wanna duel you!"

"A duel?"

"You dared to-"

"Yeah yeah, okay! Sure! I accept your challenge."

"Grrr!"

...

"Ahhhh!"

"Rinkah?"

"Why can't I beat you!"

"Don't feel bad, I've fought things you couldn't possibly face without being paralyzed in fear."

"Oh? Is that a challenge?"

"Don't Rinkah. Don't you fucking dare!"

"Uhh..."

"The beasts have taken enough from me, I won't lose anymore!"

"..."

"Rinkah? Are you okay? I didn't mean to yell like that."

"Damn. Anyone ever tell you you can be pretty terrifying when you're angry?"

"Yes. Common village folk though, so I didn't take much heed of their words."

"Hah. When you yelled, I felt like a chastised naughty child. Can you never do that again?"

"Yeah, no worries."

"Oh, Alcruz? I forgive you for touching me."

"Oh? Thank you Rinkah."

"No problem."

Alcrux and Rinkah have reached A-Support

"Hey Rinkah."

"Saying something other than just my name? Who are you and what have you done with the real Alcruz?"

"Rinkah..."

"There we go. You're back."

"Can I ask you something?"

"Shoot."

"You remember our spars?"

"Yeah, what of them?"

"Why are you so intent on beating me?"

"Well, it has something to do with pride and another with ability. You're undisputedly the best in camp, so if I could beat you, that makes me the best and proves I've improved so much from where I started."

"People think I'm the best fighter?"

"Yeah. You never heard the maidens muttering your name and fainting, muttering about the reaper with a scythe? Trainers using you as point of examples of being the best of the best? Hell, even Ryoma trains hard to one day defeat you."

"I should really pay attention."

"Don't pay attention to the maidens."

"Umm?"

"I've already told them you're taken."

"Well, I'm-"

"By me."

"You what!"

"Yeah. Congratulations, you earned the heart of the princess of the Flame Tribe."

"What? Rinkah, how did this start?"

"Well it began when you groped me. You have incredibly skilled fingers."

"I-"

"Shut up. Let me finish. Truly, it's because of your power and your humble nature. You aren't fooling anyone, I know you hear everyone when they praise you. Yet, you ignore them as though they never complimented you."

"..."

"You're also easy on the eyes, and the armor may cover your entire body, but I can see your muscles on your arms, and it's delicious."

"..."

"So, I just poured out my heart to you. I hope you don't break it."

"No. I won't. In fact, I feel the same for you, dear flame."

"Dear flame? You haven't even put a ring on me, and you've already given me a pet name. You're just a player, aren't you?"

"Uh, no?"

"I'm joking. Still, I'm glad you feel the same for me as I do you."

"Yes, I am as well. This was an unconventional proposal and reveal by both of us."

"Agreed."

"I'll go and buy a ring, I'll bring it to you soon."

"Please, Alcruz."

"I love you, Rinkah, my dear flame."
