Cupid, Kucin, Guz and Blade were told to wait downstairs as the adults and the fairies goes to one of the room in the second floor. Currently all of the unconscious attacker and one corpse are place there. The room have also been empty by putting all the furniture into the item box. 

Azumi uses darkness magic to darken the room even more and place a lighten candle in the middle of the empty roo and ask one of the fairy with psychic element to increase their five senses and emotion

"Huh, why is that you ask me to enhance their sense" [Psychic fairy]

"So that they will become more aware of what's happening around them" [Azumi]

"Doesn't that put them in more of the advantage" [Psychic fairy]

"Not if I use it to my own benefit" [Azumi]

"?" [Psychic fairy]

"To put it simply, with their sense and emotion heighten, it would be faster to break their spirit" [Azumi]

"Strange but if you said so"[Psychic fairy]

The fairy then do what is asked. Afterward those fairies waken the unconscious men

"Huh? Where are we and why is it so damn dark here" [Long hair man]

"Oi, this thing, what is thing that bind us" [Swordman]

"It's a tree branch and it a real hard one, don't bother to even resist!" [Azumi]

"Huh, that voice?" [Long hair man]

"Now then, as I recall, you say something about enjoying the scream of my students, I wonder what kind of sound you will make this time" [Azumi]

"Screw that, I suppose to defea.. huuuuup" [Long hair man]

Azumi entrapped all of them in a sphere of liquid were the men are currently drowning, he also put off the candle light to further stimulate the sensation of drowning in a bottomless ocean. He do it for full three minutes and Filaurel already fidgeting about it

(Azumi, they will die!) [Filaurel]

(No they won't) [Azumi]

(Huh?) [Filaurel]

(I forgot to tell you guys about this, this is a breathing liquid, Mr Fei and his team created this technique so that there will be enough air in the liquid so that they won't die due to lack of oxygen) [Azumi]

(But they look like they are struggling) [Filaurel]

(True, liquid is still denser than air, so it's only natural that they will struggle, and with them having no idea that they will not die, this give off the feeling of impending doom, furthermore with the heighten sense and emotion they will feel even more helpless) [Azumi]

(I see, that is a cruel thing to do) [Filaurel]

(They got what they deserve) [Azumi]

Azumi then release the spell and lighten up the candle once again

"So then gentlemen, I believe you know what will happen if you don't give what I want" [Azumi]

"You want some information right" [Long hair man]

"Nope, it's something more" [Azumi]

"WHAT MORE DID YOU WANT!" [Long hair man]

Thus the second round begin and Azumi said something loud intentionally

"Edward, please release those snapping turtle" [Azumi]

The other were visibly confuse to his word, Suddenly mentioning the name of their king out of nowhere. Azumi simply use an ice magic and make multiple fang like structure, it then go and bite the attacker, with that, their fear intensify. After releasing the magic

"Now then, where was I?" [Azumi]

"What did you want from us" [Long hair man]

"Ahh, that's right, I want you to work for me" [Azumi]

"""""Huh?""""" [Long hair man]

The five men become visibly confused

"Short version, I want you to betray the dark guild and help me destroy it" [Azumi]

"THAT IS... huuuupppp....." [Long hair man]

The third round begin, this time, Azumi uses gravity magic underneath them to give off the sensation of falling deeper and deeper into the bottomless ocean, and once two minute have passed, he make the opposite spell, to give off the sensation of being dragged into the surface before releasing the spell. Of course the snapping turtle bonus is also added

"This is not a request, its an order, and you have no said in this matter understood! [Azumi]

Those guys simply nodded with their lifeless face

(Just one more push) [Azumi]

"Oh, I forgot, you guy doesn't need to be alive for this order, Men! Put them in their coffins!" [Azumi]

"WAIT, NO, NO NO NO NO NO!!!!" [Other]

Filaurel, the three from the first knight squad and Azumi himself put them in an earth coffin made out of magic, they try their best to struggle but to no avail, once inside, the drowning sensation is replicated, and after ten minutes have passed, one by one the coffin is opened and Azumi uses a spell

"Oh Psychic, govern this mind in my stead, Mind Control" [Azumi]

The psychic fairy also aid in this process and once all the five men were put into a spell, Azumi use memory dive, again with the psychic fairy help

(Now then, show me how this corpse guy used to behave) [Azumi]

After some memory dive

(!) [Azumi]

Azumi get back into his senses

"How was it" [Filaurel]

"This corpse guy is a mute person with a timid personality" [Azumi]

"That's convenient" [Filaurel]

"Very convenient" [Azumi]

Why is it convenient? Azumi wanted to disguise himself as the corpse guy and infiltrate the dark guild bases with the now five controlled men, as this spell required Azumi to be there at a certain distance, disguising himself as one of them is a good option.

"Now then, time to infiltrate the dark guild base!" [Azumi]
