First, he had to kill a few important people. The target that he was originally going to kill Borick, Sinbad decided to send out a clone to deal with him and his Rakshasa Demons. Next target is Syura and his group Wild Hunt. Sinbad was going to deal with them himself as he stormed the Capital. The one after Syura would be Budo who would be in the heart of the palace. Sinbad would kill him by himself also. The penultimate target would be the Emperor and his Imperial Teigu: Shikoutazer. Sinbad came to the conclusion to just capture the Emperor and hand him over to the Revolutionary Army similar to the manga. And last but not least, Honest.
