Did you try to test it vs a full immune opponent team to verify if 4 standard atks that doesn't get access to the special tag one will generate the chakras normally ?
Which Ay we're talking about, 4th Raikage or 3rd Raikage? pretty much this annoys me when people mention Ay / A, since all Raikages are called A's / Ay's.
Ay 4th 4 standard atks nothing to do with Ay 3rd here.
