After a tragic accident that left her twin sister suspended in time, Bai Winchester assumed her family's legacy —and curse— of wielding the mystical Ice Blade.

Haunted by her personal tragedy, she vowed use her powers only in the defense of others, and not give in to the blade’s murderous impulses.

Reluctantly agreeing to join UNION's Wildhüter team as an instructor, she fights a constant battle between duty and instinct,
hoping she can control the Ice Blade long enough to both free her sister from her timeless slumber, and free her family of its influence by destroying the blade forever.

April 2nd.

Today, Xue bought glasses from a merchant that came to the village.

Grandmother told Xue that they suit her, and praised her.

Because she was wearing them for the first time, Xue looked quite dizzy.
I was surprised that a genius like Xue couldn't do it.

I really, really like Xue for the way she is.

May 13th.

Our clan is one that boasts having a long history of assassination.

If a king were to do bad things, then our clan would secretly pay him a visit.

Although we do not partake in assassination anymore due to the change of times,
me and Xue train vigorously so that our skills will be passed on to the future.

I'm going to work hard to catch up to Xue!

September 9th.

We are a prodigy and a mediocrity born on the same day. On the same day we will dance upon the stage.

Even when I had awakened to the Phase Force, I was never able to beat you.

15th birthday. Getting to be the official successor.
Congratulations, prodigy of the clan.

If it wasn't for that weird sword, would our fates have changed?

July 15th.

The ice that has imprisoned Xue still has not melted to this day. Every time I look at the mirror, I see her crimson eyes.

It's all my fault for being jealous of the genius. I had made her that way. I had imprisoned the genius of the clan with my own hands.

Xue, how can I possibly atone for my sins to you? I'm not even able to properly be your replacement.

I feel like you are being reflected in these crimson eyes.

Please, come back, Xue. Please...

July 16th.

Xue, it's been 5 years since you've been imprisoned in that ice. Even the summer heat cannot seem to melt the time that imprisons us both.

I've become an adult, yet you're still trapped to the time back then. I wonder when this disparity in time will ever end...

I'm sorry, Xue. I think I'm going to travel far out. I'm going to go to this place called UNION in the outside world.

I've heard that it's the place that knows best about Phase Power and this weird sword that you picked up.

I'm sorry, Xue. Please just hold on for a little more. I will find a way to save you, no matter what it takes.


  • Bai's dance emote is from Hoshino Gen's Koi Dance.
  • Bai's chinese name is 白, which translate to "White".
    • The Blade of the Ice also has the chinese character 白 engraved on it.
      • Bai's sister; Xue, chinese name is 雪, which translates to "Snow". When both names are put together, it would spell out "Snow White".
  • Bai's clan thought of passing skills down their descendants more than anything, so it didn't matter for them to keep their last name throughout. And therefore, her clan didn't even hesitate from bringing outsiders in, if the outsider was strong and competent enough, because that would mean that they would be giving birth to stronger descendants.
    • Bai's name changed from her grandfather's line, when apparently they brought in a Westerner, and followed the Westerner's last name.
