it was an ordinary New Year's day, you decorate the Christmas tree, etc. and everything seems to be fine, but there was a knock on the door, you open the door and there is Umbra, (but how did she die already like 3 years ago, well)

Umbra: Uh well, hello...Happy New Year...... hero....

apparently she's not happy that she had to go to you and say that when she should have killed you a long time ago
