    Meet your favorite characters? Enjoy your second chance at life?
    Well, Yuri has a better idea.
    After waking up as **Mafuyu Asahina’s long-lost older sister**, armed with knowledge of the plot, and a mysterious System rewarding her for making Mafuyu happy, Yuri discovers her new purpose in life:
    **Step 1:** Kiddnap- I mean rescue Mafuyu from Mafumom.
    **Step 2:** Spoil Mafuyu rotten.
    **Step 3:** Make Mafuyu happy.
    **Step 4:** Somehow accomplish all Steps without embarrassing myself in front of Mafuyu.
    Unfortunately for Mafuyu, her new older sister is overprotective, slightly unhinged, and has absolutely no intention of being normal about this.

    Happy Mafuyu. Happy Life.
