Aria an elf girl who is an adventurer with her cat name "Tama" where Tama always protects her everyday. She always heads to the dungeon to raise her rank as she is a D rank until one day as she comes back from the dungeon and a man named Kussman came and had put a quest to exterminate Tama but he gave her a choice. A duel. If he wins she becomes his wife and if she wins he'll stop everything. Of course she accepts and he laughs as he spoke

"Because she is a lower ranker. I gave her a special need for support. One person! Anyone join her"

Of course no one can join because he is quite strong while she was standing there looking at anyone for help
