So here's a theory I've formulated based on the recent events.
Spoiler showAfter the mini war at the cooking fest, both Bishokukai and IGO suffered a tremendous loss. Both bosses were pissed because they were deceived.
Ichiryuu never thought that NEO was that powerful. He thought they were just a bunch of rich people who wants to get high quality ingredients.
Midora on the other hand was also worried about NEO. He wants to crush them to reduce his rivals for God.
Just outside the NEO castle, both Ichi and Midora arrived. They looked at each other but said no word.
The gates opened and a voice told them to enter. The two walked inside until they reached a huge door.
It slowly opened and a man wearing a jester suit appeared.
"So it was you Joa that's behind all these." Ichiryuu said.
"I should have killed you back then." said Midora.
"I'm sorry to disappoint you two but I'm a mere servant here. You should save your anger for the boss."
He then lead the two to the hallway. And at the end of it, a throne was facing backwards. There was no light in the room but something is flickering in front of the throne.
Then Joa announced. "Your highness, the visitors that you're expecting has arrived."
The throne slowly turned towards them. But it's still too dark to show who's sitting on it. It's just a shadowy figure but they saw him stand up. Then snapped his finger and the lights turned on.
The two were shocked upon seeing the NEO boss.
In front of them, there stands Zonge with a game console joystick in hand.
He pressed some buttons and Joa started to dance and juggle. He pressed some more and Teppei, Shigematsu, Kousairou, Kuriboh, Zaus and other defectors came out dancing as well. And they all wear ballet tutu.
Both Ichi and Mido were so shocked that they did not notice the man behind them. And it was too late because they've already been knocked. They both fell down but before they lost consciousness, they saw Jirou's face smiling at them...
