He told her mixed-blood wasn't inferior to pure-blood and they agreed that if he can show something to surpass a royalty member, he will be allowed to be a team leader and Anos activated a contract spell, which surprised Emilia as she didn't see him draw a circle. He went to the spell and explained it had a flaw and fixed it, looking at it, Emilia realized the spell got better and Anos explained it became twice more powerful. Having no choice, Emilia approved him to be a team leader.

They told Isabella to run away, so she ran to call for help. The girls matched their power together but soon got blown away by Emilia's flames.
