Raphael just inflicted fatal damage to the Typhon by making a huge hole in its chest. He could use his Nuclear Beam again and again and spam it to the monster, but he decided not to so that his sister could showcase her skills more to the audience, their parents.
As her brother, Raphael wanted to help Louise improve and get stronger. Fighting a monster with a thousand levels was a great opportunity for her. If Raphael ended the battle so soon, Louise would not exert her full potential throughout the battle.
Currently, both of them were standing next to each other as they watched the Typhon slowly heal itself. They had been standing still for minutes and had already spent some time with Claire and Mylene in tea before going back again.
The internal organs and flesh had been restored, as had the deep cut that Louise inflicted beforehand. The monster was currently and painstakingly in the middle of its skin and scales restoration.
