Ahhh!! That One!!! It's Pretty Hard U.U...The Toughest Boss I Fought
But I Could Beat Him In My 3rd Battle
^...First Of All...Get All The Other Kaisers,So Then When He Uses His Shields,Only With Them You Destroy Them
Use Protective Ether Spells And Speed Up Spells,And Have A Character Guarding And Healing When He Has To...I'd Say You To Finish Every Sidequest And Level Up A Lot...With Dark Kaiser(The One You'll Get) You Will Destroy Every Common Monster...But If You Go To Fight Omega System In The Facility(Where T-Elos Fought It Too) And You Win(It's A LAAAAARge Battle) You Can Get The Final Kaiser,Taht Can Damage More Than 1000000,Believe It
