"A bone knife? Part of her? Are you saying, grandfather…"
Aoi's eyes widened in disbelief, as this was something that even she didn't know about Fiona despite them knowing each other for five years!
"When Fiona was born, she was born with the bone knife inside her body. It was a strange birth defect, and it caused her baby self to suffer from insane pain as that knife's sharp edge slid against her organs.
"The doctors had to immediately remove it from her body, and instead of getting rid of it, her parents kept it as a reminder of that scary, yet special night.
"It doesn't matter if the bone knife is no longer part of her body. It once was, and based on the rules, she is allowed to use it in the match!"
Master Arakawa said.
Fiona twirled the bone knife in her hand, and it was clear that her mastery of the knife was extremely high.
