Sera comes across as a kind, level-headed person who is caring toward those she interacts with and welcoming to even demons such as Charlie and Vaggie. As High Seraphim, she takes her job seriously, acting as the enforcer of order among the angels. This extends to her abiding civil behavior, as she seems upset when Charlie loudly curses in the court. She holds a preference for negotiation over violence when it comes to conflict, such as when she is willing to hear Charlie out on her plan.
