Realm of Darkness.

It has been a day since Melromarc was in ruins and their queen got corrupted by the darkness however the forces of darkness can't rest.

Currently the Council of Kurai are looking at the world map of Litavis with three locations marked red which is where the forces of darkness attack.

Hades: "So what now? Union lost two powerful allies: Atlas and Melromarc" he said.

Bowser: "I say we strike at Musutafu! After all they are getting students and many heroes from that city" he said.

Ganon: "For once Koopa you and I agree on one thing" he said.

Jafar: "We need to make sure those light keybladers won't interfere as they already intervene with the princess of light Melty" he said.

Dark Spawn: "Thus why I believe we need to attack all of Shizuoka Prefecture" he said.

Him: "A full assault would completely destroy the city. I'm in" he said.

Vlad: "I agree besides these heroes stand no chance against a full on war involving our forces of darkness" he said he said.

Potema: "When do we strike?" She said which Dark Spawn chuckled.

Dark Spawn: "Now" he said.

Musutafu city.

Currently the civilians and heroes are enjoying the peaceful day when suddenly thousands of heartless, nobodies, Unversed, Nightmare Eaters, monsters, ghosts, and all sorts of forces of darkness appear.

Immediately the heroes rush in while the civilians run but many more monsters appear and easily kill the civilians thus turning them into heartless and nobodies while the fear of people creates unversed.

Heroes: "Where are those Keybladers!" They think as they try defending the civilians.

However what the heroes failed to realize is that the two keybladers and their students are busy defending the rest of Shizuoka Prefecture.

Watching the whole destruction of Musutafu is Dark Spawn who smirk as the heroes are failing in saving the civilians while many buildings are being destroyed.

Dark Spawn: "Ah I do just love the smell of fear" he said only to create a barrier that blocks a fire ball.

Dark Spawn then looks to see Endeavor who is glaring at him yet Dark Spawn can sense a lot of darkness from Endeavor's heart.

Endeavor: "You villain shall pay for destroying my home" he said and about to attack only to gasp as Dark Spawn stab him in the chest.

Dark Spawn: "Let's see how well you can handle as a Heartless" he said then Endeavor darkness devoured him yet he became a new Heartless.

An: I don't own the art also Endeavor heartless looks like that but there is a heartless emblem on his chest.

Then Heartless Endeavor roared before joining the destruction of Musutafu which Dark Spawn smirked.

"I wonder how Union would react knowing that the number 2 hero of Japan is now a heartless" Dark Spawn said then vanished.

An hour later.

Both Union and the Keybladers, who finish defeating many forces of darkness, arrive at Musutafu only to see nothing but ruins and flames.

All Might: "I can't believe that Endeavor Heartless can do so much destruction" he said.

Riku: "Dark Spawn must have unleashed the darkness within him. Now he is nothing but the darkness in his heart" she said.

Ozpin: "There must be a way to restore him" he said but Riku and King Mickey look at each other.

King Mickey: "I'm afraid that it is difficult since we don't know if his Heartless and Nobodies can be beat" he said.

An: ok so to those that don't know if a person has a strong heart and will they become heartless and nobodies but united upon defeat they reform into the person they used to be.

Nezu: "I see well we don't know where his nobody is but we know his heartless is with Dark Spawn" he said.

Riku: "For now we keep training the chosen keybladers as clearly Dark Spawn won't stop" she said then everyone leaves.
