Yeah, but what is considered outside? And what is considered inside? I get why Issei's Cardinal Crimson Promotion is considered ex side as it uses an evil piece to be achieved or why Saji's balance breaker is considered ex side because it uses four sacred gears. I however don't understand what an abyss side could be and I thought Empireo Juggernaut Overdrive would be a candidate based on what I do understand. It is basically just an evolved form of Divine Dividing Scale Mail without anything external. Why would Vali's Empireo Juggernaut Overdrive be considered ex side? And if it is explained in the novel already why the Empireo Juggernaut Overdrive specifically is considered could you please just tell me the volume number (and chapter if you can)? I haven't caught up with the latest volumes.
