I'm sure to get the luck of my fairy wife

(All the female protagonists are included) I was just a minor character at the beginning of the game of the righteous elder brother? Don't panic!
Wife, please lend me some luck!
The arrogant fiancée breaks off the engagement and rises!
The gentle little junior sister is smart and steady!
My little fox is soft and cute!
There is also a witch who is greedy for my body!
A steady one!
…Young Sword Master, please listen to my explanation! Put down your sword! Don’t step on me!!!
