Genjutsu Shield

The Genjutsu Shield (Genjutsu Tate, 幻術盾) is a kekkei genkai unique to the Shimizu Clan that grants members the advantage of never witnessing, hearing, or feeling an illusion. Those who inherit this can surpass all genjutsu, no matter the source or power within it. However, they cannot sense when someone attempts casting a genjutsu on them, or those they are around. From the moment a clan member is born, the parent tests several genjutsu on them to test whether they have this kekkei genkai or not.
