    Summary

    Ever since you were granted a mysterious gem as a young student, you've been given the gift of being a Magical Guardian, protector of Justice!

    For a while, your powers weren't really needed..so you mainly focused on living your daily life.

    ..At least, until some edgy skeletons came crashing into it.

    ---

    Mainly intended to be a comedy/unserious, but there are also good amounts of lore and seriousness at the same time. It's like 50/50

    No consistent update schedule, I just kinda add onto this when I feel like it, I hope you guys enjoy!

    All textboxes are made with Demirramon's textbox generator.
