Some years after the fight between Oga and Fuji, the friends gathered once more. They discovered the artificial demon created by Tatsuya. There's several options for this discovery:

********Two years after the end (the last chapter of the manga), the demon's contractor (and their demons) felt a spike of demonic power that was like a mix of all their energies together. That would imply an error from Tatsuya in suppressing his demon energy. They would confront him and discover that he cloned their demons. A war would ensue with Tatsuya against all. It could end by his defeat (they could imprison him in the demon world for example) or his win and subsequent centuries of boredom (because yes demonic power fuck with growth).

********He was betrayed. Whether by Shizuka, Ushio or one of his employees. Same here. A war with some emotional talks about loyalty and treason, good or bad,...

********This is the best option for me. After all his training and preparations, he was disappointed by how easily he bested them all. He'll then decide to play a little game. He could decide to conquer the demon world: he could be serious or not it doesn't matter. He knows that Beelzebub III, and the monsters of his generation are still stronger than him (or at least at his level). So he'll take eight years to train with his demon, build an army of loyal soldiers (not with Beelzebub power), and train them, create artificial demons for them and all that. When he will be sure of his powers he will start the hostilities. It will be a strategical war with spies, kidnappings, skirmishes, seduction, torture, rape, corruption and all that.The final result doesn't matter just the process. There would be many deaths in that war and it could even last for years.
