I haven't watched "Guarding Sweetheart" for many years, and I have forgotten a lot of it...
Therefore, in order to keep the difficulty level low, only Hikari Ichinomiya appears frequently. The other guardians are seniors, but they will also appear. After all, they still live in that area...
(Ps.: Since the 102 episodes of the animation are all self-created, the characters are not included. In addition, the author has not watched Guardian for a long time, although he has watched them all... If there is any discrepancy, you can raise any objections.)
