(At Lexcorp, Lex Luthor and Vandal Savage are seen holding two Wonder Ride Books.)

Luthor: This Saber guy proved to be a bigger threat than I have anticipated. He beat Darkseid like he was nothing. Not even Superman had such power.

Savage: Poor confused Luthor... unlike Superman, Saber didn't hold back against Darkseid. He knew what he should do the moment he witnessed what the so-called New God could do. That's why I decided to get these books for us. To give us a fighting chance.

Luthor: When do we start?

Savage: (smirks) We already did.

(Meanwhile in a forest, the Justice League is seen fighting both Klarion and Queen Bee, and then Kamen Rider Buster prepares to strike Klarion.)

GENBU SHINWA! DOGON! GEKIDO RANDOKU GEKI! DOGON!

(Rocks from the surrounding gather onto Dogouken Gekido, enlarging the sword to a massive size. Light orange energy then covers the blade before Buster performs an enhanced downward slash which destroys both Queen Bee and Klarion.)

Batman: We fell for a trap.

(The Justice League gets confused until Superman gets shot down by a kryptonite beam. Batman dodges a shot directed to him, and then someone uses some sounds to bring the heroes down. And then Black Beetle shows up along with Vandal Savage and Lex Luthor.)

Superman: (groans) Luthor...

Wonder Woman: You've been really busy, huh?

Vandal: Yes, we have. But now we're taking this!

(Vandal picks up the Dogouken Gekido and removes the Genbu Shinwa Book from it, reverting Shinichi to normal.)

Shinichi: N-no.

Savage: (to Black Beetle) Take them all to their cells. We'll use our own powers to deal with the Sword of Logos.

(Black Beetle smirks as he takes the entire Justice League to their cells.)

Savage: The world will be ours.

(As the screen fades out, the title is shown.)
