Re-grammar this.

I would switch Daki to creative mode because if bbg suffered a first loss and began to yell, directing Gyutaro to take action. As a result, he'd either rank her in Unreal or switch her to Creative Mode.

To improve the grammar of the given sentence, you can rephrase it as:

"I would put Daki in creative mode because bbg would get angry if she gets lost at first and scream until Gyutaro does something. He would either promote her to Unreal ranking or put her in creative mode."
