He practices his magic in secret, preferring to have his family believe that he is weak. However, his younger sister, Charlotte, discovers his strength, and with the assistance of Flay, Haruto protects her and the rest of the Zenfis family from harm. With a shifty plot stirring in the kingdom, Haruto only wishes to stay inside and watch anime, but it seems he will have to use his magic to keep the family that took him in safe.
