Failed
A sister ponders on what if...
If she was a little stronger; if she had been a little more determined, a little more brazen, a little more headstrong; would she had saved Souseiseki? Sometimes, Suiseiseki couldn't help but blame herself. If only she could have been half as competent as an older sister as Lunamaria; or a more supportive but firm younger sister like Meyrin. Maybe, if she had summoned up half the courage of what the Hawke sisters had, she might have convinced Souseiseki to stop participating in the Alice Game, to leave that mean, rich old man's rose garden, and today, she might probably still be alive, with her Rosa Mystica.
War is terrifying, fighting your own siblings is even worse; but there was nothing even worst than knowing that you could have saved your sister and yet you failed.
Just entertained the thought of having the Hawke sisters as Suiseiseki's medium;and how their mere presence may sometimes invoke the loss of Souseiseki, and a few 'what if's of a different ending.
