@B214 relax I know it can be annoying when people say stuff like that but ignore it I have been accused of the same thing. I personally find the fact that Issei loses is a good thing especially because he doesn't lose without reason, Cao Cao's BB is designed to defeat people stronger than him.

Le Fay teaching Issei magic lol, Le Fay might be a super genius but even she can't perform miracles. The most advanced magic I can imagine for Issei would be breathing out things other than fire and maybe "transferring" it to cover his fists.

The Ascalon thing I can imagine Issei using it as a lance(ascalon in some stories is a lance) but swordsmanship is impossible

Note both of these examples are most likely impossible for Issei to achieve unless someone were to suggest it. Issei is to busy with achieving the next level of Dress Break and Bilingual(might be misspelled) the most noble magic ever made.
