Here a question does Irina really love Issei as a childhood friend? Well it’s feel   like their relationship is forced when her introduction in vol 3 she feel like threating Issei and during their duel she wounded Issei   with her Holy sword. Does if person who you are love with reunited after years latter does you attack him with Holy sword even if he is pervert. Take look at Rias and Akeno they are love with him and care for him and they never wounded him.

Irinas intentions are unclear from the start.
