( Kalawarner's POV )
Ranko ran to my side and pulled the golden chains that restrained me, they put up a lot of resistance but Ranko had a lot of brute strength, When I was free I tried to run after the reincarnated but Ranko stopped me.
Ranko: hey calm down he's not going anywhere, we have to deal with the students first.
I turned around and I saw the girls being overwhelmed by the enemy, We were clearly stronger but they outnumbered us and we had to be careful not to kill them.
I took a deep breath and helped stop the students, in a short time we dealt with the normal students leaving only the young devils, two devil servants of Rias, and three of Sona, judging by the way they fought we were fighting against a knight, two rooks and two bishops.
Kalawarner: Haruhime, Ranko, take care of the two rooks, Mittelt, Asia, take the bishops, Lilith supports and protects Feli, I'll take care of the knight.
'Understood'
Issei: Hey what do I do?
Mittelt: Do what you want just don't get in the way.
The two bishops started firing magic attacks and Mittelt shot them down with his dual machine guns, she was using phrasium-tipped bullets that could absorb and cancel magical attacks, Asia took the opportunity to get closer and Issei decided to help her, Asia had a silver spear with a modified phrase core near the tip that absorbed magic attacks, She blocked an attack with her spear, closing the distance and incapacitating a bishop with a blow to the back of her head, Issei was having trouble getting close so Asia tripped the other bishop with her spear and Issei was able to land a hit, two down.
On the side of the rooks, Haruhime was fighting against Koneko and Ranko took the other rook.
Ranko: [ Izanagi ]
Ranko used her powers to summon a humanoid creature with black clothes and a sword with an extra long handle, this Persona could use lightning magic and the rook was being overwhelmed with attacks while Ranko calmly walked towards her and when she saw an opportunity she knocked out the rook with a powerful blow.
Haruhime and Koneko's fight seemed like a mirror match, Haruhime could see all of Koneko's attacks and she matched them with equal power, fists collided with fist, Haruhime was completely fine but Koneko soon couldn't lift her hands anymore, then Haruhime put her fingers on Koneko's forehead and she paralyzed her with magic.
On my side, Kiba tried to attack me using his maximum speed but I could easily match him, When our blades collided it was obvious that I had the advantage in power, he tried to put distance but I didn't let him get away, I shot him in the leg at close range with my shotgun, normal bullets won't do much damage to a devil but that put him on his knees and I finished him off with a kick to the head.
Issei: hey don't you think you guys went a little overboard?
Kalawarner: Asia can cure them all, let's move.
Haruhime and Ranko accompanied me and we climbed the stairs of the mansion in search of our objective, the others stayed to watch the students while Asia healed them, Her spear also amplified the power of her sacred gear and was able to heal them all at the same time.
I saw where our target had run so we quickly found him trying to break his way out of the mansion, the barrier also blocked magic from entering or leaving so teleportation was impossible.
When he saw us he tried to use those golden chains again but that wasn't going to work this time, We dodged and Haruhime returned to her original form to use her special magic [Uchide no Kozuchi] that gave a powerful Buff to both of us.
I enchanted my twin blade with lightning and threw it at the reincarnated man, with that force and speed of rotation that should have been a lethal blow but he took out a sword and stuck it in the ground.
???: incursio!
He shouted the name of the weapon and a dragon-like creature appeared from the ground, that stopped my attack and then he was covered by armor.
Ranko: You're finally going to stop running, huh?
The reincarnated man rushed towards us but I wasn't worried, he had a couple of good weapons but his battle experience was almost non-existent, I looked at the ring on my left hand that Yuuki had given me and after putting a smile on my face I activated one of the magic infused into it.
Kalawarner: [Boost] x30
I used my left hand to send him crashing with a powerful punch, then I called my twin blade at me and Ranko took the sword of her Persona Izanagi, We both threw our weapons at the reincarnated man, nailing him to the wall by his shoulders, To finish it off, I opened a hole in his chest with a final punch.
When he finally died a golden marble fell to the ground and when his armor disappeared a cracked sword also fell, I took everything he had, the marble, the sword, and the golden chains.
Kalawarner: mission accomplished.
I took my twin blade and walked back to my family at the entrance of the mansion, there we saw that Asia had healed all the students but none of them had woken up, that didn't seem right.
I took my phone and called Ema to bring the ship here and I started carrying the students out of the mansion.
Issei: hey when are they going to wake up?
Kalawarner: Soon, we need help from someone else.
Mittelt: Your work here is finishing, you can leave now, and do it quickly.
Issei: I'm not going to leave my friends.
Ignoring Issei's screams, I kicked the door open, shortly after the Iwafune ship landed in front of us and Ema and Shizuka came out, Without having to explain the situation to her she checked out all the students and she gave me a knowing look.
Ema: yep, I can leave them like new in a moment.
For some reason, the mind control had not disappeared but Ema quickly resolved that the only thing missing was to return these students to their homes.
