I am breaking flags as the heroine's older sister in an otome game world.

This is the world of an otome game that I was completely obsessed with in my previous life. And I was reborn as the cute, cute, and even more cute heroine's older sister. My younger sister is my wife. My sister is so cute that living is painful. Just kidding, it's fun. In order to spend such a sisterly youth just the two of us, I've decided to break the flags of the capture characters. This is a story about a protagonist with heroine supremacy who interferes with the capture characters, goes full big sister mode, or even risks being captured herself. Updates will be quite irregular, but thank you for your support. May 1, 2017: We're pleased to announce that this work will be published by Kadokawa Beans Log Bunko Alice. Publication is scheduled for July. Please check the official website for more details. As for the web version, I plan to continue at my own pace as before.
