These past two weeks, search for Kisuke and Yoruichi kept going until Aika and Koneko's relationship with him was revealed. The current leaders did their best to protect the two by denying their relationship with Kisuke and Serafall even used her connection to hide Aika's parents from all of this.
Denying relations worked since a lot more rumors and small accusations against Kisuke that most of them can't be taken as true.
Still, Kisuke's name would sooner or later become a household name that would scare off children in the Underworld.
Aika and Koneko were under the care of Rias Gremory and kept trying to teleport to the training ground, but with restrictions in place, they couldn't and they also have to be careful so that others couldn't see what they are doing.
And earlier today, Kuroka arrived and tried to help both Koneko and Aika with their token, but even with her extensive knowledge in space magic, she also failed.
It was until they gave up that the restriction within the training ground was suddenly lifted and both Koneko and Aika felt it with their tokens. Kuroka finally got something with her expertise as she was able to include herself when Koneko and Aika were teleporting away.
And that is how they all arrive here.
"That's all I'm aware of..." Kuroka ended her story.
Kisuke nodded at her and let go of Aika and Koneko and turned around to walk away.
"Wait! At least tell us what happened? And where are Yoruichi-san and Sona-kaichou?" Aika shouted at him.
"They're inside, and they are already fine..." Kisuke didn't turn back and continued walking away.
"What about you? Where are you going?" Aika asked again.
"I'm fine... Well, maybe not so much. And I'm about to do something stupid..."
"Something stupid... is it? Then make sure that you come back before dinner!"
Kisuke waved his hand back, "I will... And Medusa, I'm craving for some sushi."
Medusa smiled with her real name being called. She bowed towards him and said, "You can expect a large variety of sushi later, master."
Kuroka, Koneko, and Aika were surprised when Kisuke called her real name and suddenly recalled the infamous monster called Medusa from Greek legends and the Mount Olympus accusing of releasing a very dangerous criminal. If what they are thinking is correct, then the criminal of Mount Olympus is such a cute little girl.
Before he goes away, Kisuke sealed the training ground again since he already knew that it isn't safe outside and he would probably take some time to prepare here in the training ground.
After checking everything is working fine, Kisuke took a deep breath and removed all the seals he placed on the Hougyoku.
One thing that he can't compete against Aizen is 'emotion'. And 'emotion' is a big key in activating the Hougyoku properly. Aizen's ambitions gave him enough 'emotion' to let Hougyoku read his deepest wish of transcending and that is something Kisuke couldn't do as he would always calculate everything based on their value.
Which is why he's afraid to use something that uses his own 'emotion' to function. But this time, it's different. Pure and unbridled rage will help him utilize this cheating gem, 'For hurting my women... I'll annihilate you.'
Kisuke teleported away and arrived at the place they were poisoned and almost died.
All the Grim Reapers working on the damaged ritual site stopped and looked towards the uninvited guest.
Nyx, who is supervising the restoration, shuddered when she saw the familiar figure that she firmly believes already died, "Y-you... How are you still alive!?"
Manifesting every darkness she could, Nyx got ready for a life and death battle. However, she didn't attack immediately as she has this weird feeling that she shouldn't make him her enemy at any cost, and she trusts these instincts of her that already saved her life multiple times.
They are already enemies but she still tried to talk to him, hoping to jump ships, "H-hey... Why don't we talk for a moment...?"
Kisuke looked at her for a second which gave her another chill and suddenly ignored her entirely. Kisuke then materialized his cane and pulled out its hidden blade, aiming its tip on his chest before plunging in it.
"What are... you?" Nyx then started questioning her sanity after seeing him stab himself in the chest but when he's about to approach him, thinking that he committed suicide, she suddenly felt the atmosphere getting heavy... unbearably so.
Nyx looked around and the Grim Reapers are already kneeling and panting hard. Confused at what's going on, they tried to resist the heavy atmosphere but every single one of them failed to do so.
When Nyx looked up to Kisuke again, confusion took over her... along with fear.
Nyx's reaction is due to Kisuke's drastic change. Long pale blonde hair without its former shagginess. A white bone mask that is now covering all off his head and now with angular horns pointing upwards. Under his shihakushou is the same whiteness as his mask and a hole big enough for an arm to go through is on his chest. And floating inside this hole is purple gem exuding unknown power, 'W-what is... this!? No one told me that he's this terrifying! I have to escape!'
Nyx then tried to use teleportation magic to escape but after trying, she knew that this method wouldn't work due to Kisuke's aura causing too much fluctuation in space that most of the space magic would be rendered useless.
Kisuke ignored her efforts and started charging the biggest Cero (Hollow Flash) he can manage. From the tip of his horns, a darkness that is even darker than Nyx's darkness started to gather like an expanding black hole.
Seeing this, Nyx started to shake from fear and did the second best thing she could do which if forcefully tearing the space, 'This is bad! This is bad! Hades, you bastard! We've stepped on something we shouldn't have!' Nyx then allocated all of his abilities in tearing open space and in a few seconds, she would be able to escape, 'If I can make out of this place alive, I'll make sure that you'll never know his real identity!'
The black hole's size then enlarged to 5 meters in diameter before Kisuke stopped charging it. But instead of shooting it, Kisuke used Descorrer and left immediately, leaving the now unstable Cero behind.
Nyx was extremely alarmed by this and doubled her effort, "Please let me out of this place!!!" She shouted and that's the last thing she could say before the Cero expanded in an instant, engulfing the whole place, reducing everything it touches into nothingness. That day, a small realm disappeared.
