Well it's your choice, if you want to continue being a loser, i won't force you. For your info the BD version is just the extended version of the anime by 3 minutes of multiple scenes.

Also Xenovia isn't planning anything or rather she can't, she's just a power idiot after all, Issei and many other characters confirmed that.
