But if they knew it happened in Tokyo then why they still didn't increase the security in Kuou Town? Especially when it is the base of Rias Gremory and home to Issei, if they already met Euclid in Tokyo then surely they had to double check their security in Kuou Town? Why characters like Yaegaki or Strada just appeared out of nowhere right in their territory like that? Are they so incompetent to not think the enemies wouldn't appear again? Or overconfident?

This is a repetitive format Ishibumi using.

I don't see how, sure vol 17 has good fights but in vol 18 Yaegaki got defeated like an anti-climax, we don't even get to see Issei struggled against his bane which is holy dragon-slayer sword and they barely fought each other. Irina just pulled out a deus ex machina and Yaegaki got finished, Rizevim came in beating everyone and Issei pulled out a convenient powerup. This is nowhere as good as vol 10 or 12, hell vol 9 where Issei commanded everyone and took a shot at Cao Cao is much better due to better foreshadow.
