"He fell asleep at his desk..."
After spending the entire night working and listening to his creator's complaints, Rei experiences various emotions.
He's happy that his master stayed by his side.
However, seeing him sad doesn't please him.
At that moment, his gaze turned toward the chainsaw sword given by Gorou.
'He mentioned wanting to deal with the crows in the other abandoned church...'
He picked up the sword, then casually threw it over his shoulder.
Rei had been created to protect the laboratory and sometimes for missions related to the underworld.
Gorou hadn't created him for hunting fallen angels or dealing with human problems.
This explains the functions of the weapon he offered to the red devil.
But things have taken a different turn.
Rei no longer wanted to just protect the laboratory, but prioritize watching over the man working inside.
A bit like a chick that wants to stay close to the first creature it sees after hatching from its egg.
Thus, he decided to patrol while Gorou slept.
A small gesture, but it allows him to be a little more useful.
...
"Haa~"
After a yawn, Gorou woke up on a bed in the laboratory.
A different place from the office where he lost his battle against drowsiness.
'Rei must have carried my body here.'
He hadn't built a bedroom for himself, but that didn't mean he hadn't prepared resting places.
Especially since Alpha and Rei are supposed to stay stationed at the laboratory.
"Shit, I slept for a long time."
It was already late.
Gorou had slept not only through the morning but also the day due to mental fatigue.
He immediately cleaned himself and equipped his gear to go deal with personal problems.
'It's not really entirely the fallen angels' fault, but they're the only ones responsible in this story that I can beat up with complete impunity.'
An immature thought?
Yes.
Does he care?
No.
He's in the mode of: calming his nerves on a victim that doesn't check all the boxes to benefit from human rights.
Of course, it won't be animal abuse either.
There's nothing illegal here, right?
It's like beating up a unicorn - who's gonna accuse you?
Working with steel and talking with Rei had been effective, but destruction and hunting are the things that relax him best.
When he arrived at the exit of the laboratory hidden in the church, he found an... interesting scene.
Rei was observing a particular direction, while his usually neutral face showed a frown.
"There's a fight," he declared, pointing him toward a direction in the city of Khou.
If it were just a simple fight between supernatural creatures, it wouldn't have annoyed Rei.
However, there was sacred power being emitted in that direction.
A disturbing power for the red devil, who wouldn't even use the chainsaw sword without the symbolism it represents for him.
'Rei has incredible perception to detect that.'
Despite the praise addressed to the individual concerned, he didn't stop checking his equipment one last time.
Especially his magnetic bag.
Then, he threw Rei his spare mask.
He couldn't hide his devil identity, but he wanted to prevent his face from being discovered for now.
"I know you haven't had real training yet, but this is a crash course," he said, putting two bolts on his belt and his chainsaw sword on his shoulder.
Gorou hesitated for a moment but decided to give the extra bolt to the artificial devil.
Rei just placed the mask on his face, while the chainsaw sword emitted a chaotic and destructive scarlet aura.
A reaction caused by the conductivity of materials during manufacturing and their incompatibility with demonic energy.
Except for the mixed magical metal.
'I never would've had the audacity to give an object like that as a weapon to a devil if heaven's system was 100% optimal.'
Combining sacred elements and demonic energy? Impossible under normal circumstances, but things change.
As Azazel mentioned...
'even without god, the world keeps turning.'
The two men began running quickly toward the location where Rei had detected the use of Holy power.
They finally reached an ordinary residence, but Gorou could sense a gathering of devils.
Sure, he had neglected his magical training for his recent experiments.
But that didn't mean he was a complete novice.
'Devils, and a large number of them.'
As if reading his thoughts.
Rei informs him there are 7 people in the house.
5 devils and 2 humans.
"I see, then it would be better to attack now."
Gorou was outside, but the noise of chaos inside testified to the atmosphere between the two groups.
Crack.
After demolishing the door with chainsaw sword strikes, the master and creation duo enters the house.
"Oh~ another devil... accompanied by a human? Whatever, if he's hanging around with a devil then he's a greedy man so he's not a good person, right? So I can slice up this bad guy?"
The man was facing an old acquaintance while expressing himself... or monologuing alone?
Despite his clear madness, Gorou could see the individual's talent, and he immediately recognized him.
Freed Sellzen...

A wandering exorcist and a result of the Sigur Institute, which is a church organization.
Gorou had drawn inspiration from their research in creating Rei and the others, but with his personal touch.
'I mustn't kill him...'
The hand on his belt left his bolt to move to the memory gun.
"Rei... I want him alive."
The bearer of the ancient hero Sigur's gene.
A dragon slayer, but also an important human character in history.
He wanted those genes, not only for a future artificial human but for himself and Alpha!
"Understood, master..."
At Rei's words, a scarlet aura exploded around him.
Furniture and objects not protected by him were immediately reduced to ashes without the slightest trace.
The power of destruction.
"H... how?"
Rias's face didn't hide her shock as she observed the destruction power of her mother's clan in a stranger.
The addition of certain Baal clan traits, which couldn't be hidden by a mask, didn't help matters.
Rei cast a brief glance toward her, nothing more.
Just curiosity about the familiarity that was emanating from the red-haired woman.
Boom.
He immediately closed the distance before swinging his chainsaw sword without worrying about Kiba and Koneko in front of Freed.
Clang.
The bright sword of Holy Power met the scarlet chainsaw sword.
Surprisingly, Freed was able to hold on for a moment.
"Damn, that hurts." The destruction energy, emitted chaotically by Rei's chainsaw sword, began to wound Freed.
The man was too close.
He immediately tried to put distance between himself and Rei, but the latter pulled out his bolt.
His target wasn't Freed himself, but his ranged weapon.
Bang.
"Damn bat! You're ruining the mood," he said while trying to regain his position.
Kiba tried to take advantage, but he simply received a bolt shot to the thigh.
"K..Kiba!" Koneko immediately stood up to face Rei.
"Get out of my way, my master wants him alive." Rei didn't apologize or seek to express himself further.
Originally, he knows that Gorou wanted to kill the fallen angels.
However, the latter wants Freed in his laboratory right now.
A whim?
Yes, but Rei wants to satisfy it.
"B..bad guy!" Koneko threw an armchair toward Rei, who didn't dodge it.
The destruction aura emitted by him simply destroyed it, but...
Bang.
It had been a diversion for an attack.
The former yokai girl had leaped at him under cover of the armchair.
Despite the quick attack, Rei blocked it with his chainsaw sword's guard.
"Koneko, get away!!"
The white-haired girl obeyed, and a wave of lightning struck Rei and Freed.
Of course, Rei immediately countered it using his demonic energy without a shadow of hesitation.
"Haha~ red devil is tough. It's a shame you're evil," declared Freed as he stabbed Rei in the back.
The corrupted priest displayed a face filled with ecstasy after the successful execution of his little ambush.
He had taken advantage of Akeno's attack to use his exorcist sword and strike Rei in his blind spot.
Despite this, Rei didn't panic or moan in pain.
"...D..did I hold him long enough?"
Gorou hadn't been put forward during the entire confrontation, since he took advantage of everyone's attention being focused on Rei.
This allowed him to stay in the background, as an observer, to better understand the overall situation.
For example: Issei wounded, or Asia trying to defend him against Freed before his arrival.

Thanks to Akeno's attack, he was able to subtly approach Freed and finish it.
Everything had been planned for this moment... except Rei's wound in the back.
But Gorou didn't intervene, even though he saw the wandering exorcist's shameless maneuver.
Why?
Because he judged it necessary to hold back the slippery man.
"W..what!?"
Memory Gun.
At that instant, Freed Sellzen was dead.
The man in front of Gorou and Rei is nothing more than an empty and blank journal.
A document that Gorou intends to fill.
