Belle had arrived already in he midst of the battle. She spectated for a bit as Shiva and Ascot attacked the cloaked man. It backfired with an immense Firaga spell. Unable to react quickly enough she braced for the incoming attack. Luckily for her she, along with Amaya, was saved by a CoD created by Joshua. She was saved by the attack but needed to do something herself too. She couldn't just idly stand by and do nothing.
She saw that Ascot was heading for a straight-on attack against the cloaked figure. After Ascot would have performed his attack, at this moment no knowing which one it would be, she would immediately strike after that. She slashes with her keyblade releasing multiple enlarged shurikens of light at the opponent. After that she would rush at the opponent and make use of one of her new abilities, Time Splicer. Once she would land he first strike on the opponent she would teleport around the enemy, stopping the time to move, making it look like teleportion, and strike him from various angles and positions.
