After Angra Mainyu's defeat, Issei and Gogmagog came flying in to help Vali and Fenrir. As soon as they arrived, they saw Vali's armor in pieces as he tried to compress Hades' attack but only to a minimum effect. Fenrir, on the other hand, has had their movements sealed by trapping spells.
"I see... Angra Mainyu was defeated and you came back even more powerful than before." Hades commented at him.
Vali retreated for a bit before smirking at him, "This guy is a joke of existence. You'd actually have a better chance of defeating him if you put 10,000 naked beautiful women in front of him."
Issei stopped and thought about it for a moment before shivering from such 'horror', "Y-you might be right... I can't imagine winning against that."
Hades didn't know whether to laugh or grimace at such a stupid situation that was entirely plausible.
Vali was about to deploy his 'Satan Lucifer Smasher' with Issei and Gogmagog limiting Hades' movements, but before he could do so, a burst of unknown aura erupted from the other side of the temple and all of them were already familiar with a similar aura, "Who came here? That's not Kisuke Urahara or Yoruichi Shihouin." Vali immediately asked.
"It's Kiryuu...", answered Issei, "It looks like she learned directly from them."
Hades' ghostly eyes also darted towards the direction they were looking in and had a bad premonition coming over to him, along with regret, 'I really shouldn't have made him an enemy.'
And while they were distracted, numerous Teleportation Magic Circle behind Issei, Vali, Gogmagog, and Fenrir, revealing the entirety of the DxD Team. They had already finished cleaning up the Alliance of Hell's army and the only one left standing was Hades.
'It's my loss, huh...' Hades concluded, 'But I've already done my job.'
The new arrivals, however, couldn't put all their attention on Hades because of the aura that Aika was releasing, and only after Rias called them to focus did they properly face the Lord of the Realm of the Dead.
With the currently known strongest force in the world gathered in front of him, Hades could only laugh, "Kukuku... Wonderful... I'm truly honored to face all of you at the same time."
Dulio, the leader of DxD, stepped forward with his 10 white wings spread out, "I see that you are still very confident, Hades. But can you really laugh at this situation?"
"Kukuku... Of course." Hades held his staff with both of his hands and channeled his Divine Power into it, "After all, this is the most ideal situation."
Everyone frowned at his words and thought of how this could be the ideal situation for him. But soon, everyone received their answer, "Rias! I just received an SOS from the Alliance! It seems that Heaven is currently under attack and in need of urgent reinforcements!"
Rossweisse was just trying to send a message to authorities that the situation was already under control but found that she couldn't go through. After some tinkering with Security Magic, the connection was re-established and the first thing she received was an SOS from an ally.
Many eyes immediately returned to Hades as they immediately understood what he meant by the 'ideal' situation, "Kuku... Don't think of leaving so easily, and even if you do, you'd already be too late."
The Pendragon siblings tried prying the space open right away and Sun Wukong hurriedly sent an attack towards the space itself, but the three of them found extreme resistance from the space, 'So he wasn't just being merciful to the citizens of the city by not attacking it directly. It was a trap for us.' Thought the latter.
Issei clenched his fist and shouted, "You! What are you planning!?" Meanwhile, the others also started charging their attacks hoping that defeating Hades would allow them to leave this space, except for two people.
"I apologize." Hades replied with obvious sarcasm, "But the real point of attack isn't London, but Heaven with forces several times greater than... this..."
However, his words suddenly started trailing off when he noticed that the two people that should have been panicking the most were the calmest, and the bad premonition he'd had before just got stronger because of this.
The strangeness behind Hades' trailing voice also prompted everyone else to follow his sights toward Dulio and Griselda who were both quiet.
They wanted to ask what was going on but they wouldn't have a chance to do so as the answer, once again, presented itself.
A massive pressure suddenly enveloped the area as a familiar voice but with a much colder tone to it resounded, "I apologize too. They won't be able to make it back."
First, a black line presented itself in front of Team DxD before the dimensional fabric was torn open and revealed a 'horned monster with long flowing pale blonde hair'.
But it wasn't just his sudden intrusion that caught everyone's attention, but also the 'ball' that he suddenly threw towards Hades' feet. It rolled a few times before hitting Hades' robe. Hades looked down and met Apollo's wide-open eyes full of fear.
'The Gods that faced our team got defeated but every God that fought that group has perished... What a ruthless family.' Dulio thought while also sighing in relief. Although he acted calm, he and Griselda were actually quite nervous, but since Kisuke came here, it would mean that the problem in Heaven was successfully dealt with.
Kisuke wanted to talk with Hades some more but it seemed that Aika's side was escalating to an uncontrollable level, "As I promised, we meet again. This time, however, your skull won't end up with just a few cracks."
Hades felt depressed and gritted his teeth, "It really seems like it... But let me ask... What happened to the Tartarus?"
"I emptied it." Kisuke responded as he disappeared and reappeared in front of Hades and brought his sword to cut him down.
Hades clicked his tongue and hurriedly jumped backwards, but Kisuke's sword was faster than expected so a few of his ribs were cut. Sadly for him, it didn't just stop there as a blood-red energy arc emerged from Kisuke's sword and blasted Hades away, cracking most of his ribs. Due to his fight against Vali, Hades was already quite exhausted, so a simple attack from Kisuke was enough to put him into a very dangerous position.
Naturally, Kisuke wouldn't stop just because he's a bit tired and pointed his finger at him and charged a Cero before firing it towards the helpless God. At this point, Hades had already lost all hope and there's really no meaning for him to continue struggling.
Kisuke didn't move from his position and just continued pointing his finger at Hades who was already embedded on the rock and kept sending him devastating Ceros. With each blast, Hades would be buried deeper in the rocks while his bones continued cracking and his robes lost their purpose.
Although Hades had already stopped moving, Kisuke kept on going which made the others pity the God of the Dead, "K-Kisuke... Isn't that enough? He can't fight anymore."
Nevertheless, Kisuke pretended to be deaf in front of Issei's words and even sped up the process of recharging the Cero.
"Kisuke! Enough, please! He's not a threat anymore!" Issei grabbed his shoulder and pleaded with him.
Since Kisuke couldn't ignore him anymore, he instead returned a question, "Is there a point in letting him live?"
Issei and the rest finally got a full taste of how cold Kisuke could actually be.
As their leader, he had to step in so Dulio said, "Can you please let him go? The Alliance will be taking care of him. He still has value within the political sphere of the Mythologies around the world."
Still as cold as ever, Kisuke replied, "First, I'm not a member of your team. Second, I couldn't care less since I can't see the value in that myself."
Dulio and Issei were at loss on how they could convince Kisuke and the latter was even about to use force to stop him.
But alas, although Hades was about to perish from continuous blasts of destructive power, Kisuke couldn't do what he wanted as a Goddess materialized in front of Hades and started blocking Kisuke's attacks.
After a few more tries, Kisuke finally stopped and stared at the brown haired Goddess that was oozing with Divine Power. Kisuke squinted his eyes at the Goddess, recalling the records he had memorized, and said, "Persephone-san, is it? Are you here to rescue your husband? Unfortunately, I have no intention of sparing him."
Hearing Kisuke's words, Hades forced himself to look up to see the familiar back, "...Dear... You have nothing to do with this. Get out of the way. Kisuke Urahara, she's sinless so leave her alone."
But Persephone ignored him and returned Kisuke's stare, "I'd like to negotiate."
Kisuke kept his arm raised but eventually brought it down after careful consideration and some guesses as to why she would appear in front of him now with the confidence of striking a deal, "You've met Athena, I assume?"
Persephone nodded in affirmation, "Indeed and I promise you that you won't be disappointed. But before that..." her head turned in a certain direction, "I first would like you to stop your rampaging swordswoman and save my good friend."
Kisuke also turned towards the direction she was looking and thought, 'Looks like she really went into an 'Outrage'. Even though she's a Shinigami, her Zanpakuto spirits are still true Dragons.'
