"It's possible to overcome it with that, but it's another story when your opponent is a genius in that field and Sona is one of them" Naruto pointed out "Avoid attacking as much as possible. It's better to face counter-users with the spell-user Akeno, the technique-user Kiba or Gasper with his special vampire abilities. Everything is a matter of compatibility. Power-types are simply strong. But the risk is big for them when fighting against Technique-types." Naruto then turned to the leader of the group "Rias, if there are counter-users in Sona Sitri's group, they might run into Issei. If a counter eats up his enormous power, it will be an instant out. You need to come up with and refine some tactics for that."
