IF left home to join The Guild at a young age.
IF's two sisters Ruby Rose and Yang Xiao Long missed her very much as did her older brother Soulmourn.
One day several months after Blanc met, married and fell in love with Soulmourn, Soulmourn decided to tell Blanc about IF.
Blanc told IF that not only did IF not go missing like he thought but that she and Blanc are friends with each other as well.
Blanc then told IF to come to Lowee but didn't tell her why because she wanted to surprise IF by reuniting her with her older brother and two younger sisters.
After a heartwarming reunion Soulmourn, IF, Ruby and Yang are all a family once again. The End.
