Love at first sight (Heisuke x OC)

Chapter 55: Fury trouble

We were returning to headquarters after another meeting with Doctor Matsumoto about our counterattack. "I really hope Hijikata-san is doing alright at Koufu Castle..."
"Yeah, considering he said this is a battle they can't win I would've expected them to be back in, at most, a week's time"
"And yet we're nearing the end of February, what if he-?"
"Don't even think like that Chiyeko. Hijikata-san is the toughest man I know, there's no way he's kicked the bucket"
"Gomen, you're right. I should have faith in our Demon Commander" Just before we entered the compound, we saw a group of men running out of it. Heisuke pulled me with himself into the shadow of a tree to hide our presence from them. Fortunately, it worked and they ran right past us. "Were those men from the Fury Corps?"
"Considering that we're the only ones here I'd have to say hai"
"Gomen, that was a baka question. Anyway, where do you think they're going so late at night?"
"I don't know, but I do know that they're not allowed to leave the compounds"
"You don't think they're up to no good, do you?"
"I can only hope not, but sneaking out of the compound probably means that they're planning to do something against the rules"
"Well, what should we do? Do we go to Sanan-san and tell him something may be wrong?"
"Iie...At least, not yet. I think the best thing is to follow them and see what they're up to" Heisuke's eyes narrowed as he looked in the direction the furies disappeared.
"Right" We both headed after the escaped furies, desperately hoping that we could stop the them before they got into any trouble...Or before they caused any trouble.

It wasn't long before we heard an indicator that furies were afoot. A blood-curdling scream sounded in the distance followed by the sound of flesh being split open. Oh no...!
"Hurry Chiyeko!"
"I'm right behind you!" I sprinted after Heisuke who had burst into a run. Unfortunately, by the time we arrived at the scene, it was far too late. I covered my mouth in shock at the horridness laid out before me. This is terrible...A lurid scattering of ripped flesh and limbs were sprawled across the blood-soaked street. Four ghastly furies, clad in a thick coat of blood, sadistically stabbed and hacked into the bodies of corpses lying helplessly along the stained walkway.
"You bastards. All this...just to drink blood...They weren't even criminals or outlaw ronin! They were just people! You bastards killed ordinary citizens!" Heisuke's voice held high amounts of barely controlled rage as his fists trembled fiercely. It was understandable why Heisuke was so pissed; not only were normal people being slaughtered, but the murderers behind the slaughtering were once his fury comrades. It must be difficult for him to see the furies he's become acquainted with become murderers just so they can quench their never ending thirst for human blood...Noticing our presence, one of the furies turned to us before his blood-stained lips curled up into a warped smirk. It seemed that madness had consumed him, leaving no trace of sanity behind his glowing red eyes. All that remained was a primal urge brewed within them to kill and bathe themselves in the blood of their victims.  "They're past the point of no return. The blood's wiped their minds completely. I-I can't let 'em live" With shaky hands, Heisuke unsheathed his sword while biting his lip nervously. "Chiyeko, hide over there! Don't come out 'til I say so" Heisuke barked over at me.
"But I can fight too-!"
"These guys have gone mad for blood, there's no telling how strong they are now! I don't want to risk losing you!"
"I-I..."
"Please Chiyeko!"
"Okay, but you better not die on me!" I hide myself behind a wall. Will Heisuke really be okay...? I mean, those men used to serve nobly alongside him as allies and although they no longer see him that way, Heisuke may still see them as the men he used to eat, sleep and serve with. But if he hesitates then they'll certainly take advantage of that...I discreetly peeked my head out from my hiding place to watch, my worry for Heisuke was too great to just sit there doing nothing. Two furies now faced Heisuke. Where'd the other two go? I didn't have much time to worry about that as one of the furies let out a maniacal laugh before leaping from the ground, lunging for Heisuke's throat.
"Urngh!" Heisuke nimbly dodged the fury's strike. He turned on his heel and slipped a little providing Heisuke with the perfect opportunity to make his move. "Yaaah!" He kicked at the ground and thrust his katana into the fury's sternum, producing a gush of blood.
"Gaaah!" The fury yelped in pain and took a step back. It seemed Heisuke's blade hadn't pierced any of his vital organs so the fury still had the chance to heal. Before Heisuke had a chance to catch his breath and ready himself the other fury charged towards Heisuke. It seemed he was waiting for the perfect moment to strike at his enemy. Heisuke swung his sword to parry the incoming attack, but he hadn't reacted to it fast enough.
"Agh!" The blade caught his shoulder, tearing a wide cut into his flesh that spewed a stream of blood into the air.
"Heisuke!"
"Hey! Stay where you are!" Despite bleeding profusely from the wound on his shoulder, Heisuke managed to continue throwing wild slashes at the fury.
"But, your injury-!"
"This? This is nothing. Nothing to worry about. It'll heal up in a jiffy!" Just as Heiuske had said, the blood trickling down his shoulder stopped and the wound began to seal itself. I'm glad he's healed, but...I don't know how I feel about him using his powers...It's like Sen-chan said, every time he supernaturally healed was potentially sapping away his precious lifespan...but if he doesn't use his powers then..."Give it a rest already, you crazy sons of bitches!" In spite of his best efforts, Heisuke was struggling to land a fatal blow on either of the furies. He just swung aimlessly at the vicious pair.
