Hikari would win, no offense to Agul. Hikari has his Knight Shot, Knight Blade, Blade Blast, and Ultra Light Stream. And if Agul starts to put up to much of a fight Hikari would go into his Aabu Armor Form allowing him to deal more damage physically, and take much less damage also giving him access to his Aabu Knight Shot. Like I said no offense to Agul because he's good to but Hikari would be able to over power him.
Agul all the way,becuse one hes more badass than Hikari and two Agul never had to change forms to defeat an enemy,also agul had way more attacks than hikari.
