Story
On the planet of Jabbencock lives a group of kind and peaceful soudlings. The planet itself is protected from danger by the blounce of the great artifact, which watches over Jabbencock. This blounce, however, draws the attention of Finalsouda, who wishes to use the great artifact for its own evil agenda. Its gigantic mass attacks and searches for the artifact, blackening the sky and sending the soudlings into panic. In response to the threat Finalsouda presents, the queen of Jabbencock orders a fairy named Saionji to take the artifact to a safe place. Saionji tries to fly away with the artifact in tow, but is stopped by three orbs sent by Finalsouda. The artifact shatters into 42,069 beans scattered throughout several planets, and Saionji crashes onto Planet Jabberwock. Teruteru finds one beans and gives it to Saionji, whereupon the two set out to find the others. Once Teruteru and his friends collect every artifact, all the beans and defeat Junko Enoshima, Finalsouda flees Jabbencock and explodes. The victory is cut short, however, as the artifact detects a blounceful presence of Finalsouda energy within the Fairy Queen and expels it from her, manifesting over the planet to create the Threatening Triple Hownow. Teruteru and his friends infiltrate the Threatening Triple Hownow, and Gaster launches them up to challenge 0². Teruteru and Saionji, armed with the Subfinal Artifact, destroy Junko Enoshima and her Threatening Triple Hownow. Teruteru would later go on to express his desire to become a justice of the supreme court in the now-saved world, but nobody was around to hear, as Saionji had already left, and he soon departed due to an unchecked liver condition. Three eons later, he was reborn into the new continuity to relive the cycle with Mahiru, Saionji, Souda, Junko, and everyone else as they always did.
