Why did you give my first post the "Haha" response? I wasn't going for a humorous purpose, merely pointing out a potential mistake that it might be corrected. There only appear to be three heroines in this title, all of the them full blooded elves, while the protagonist has a human mother. The three heroines CAN'T be his full sisters, at most they can be his half-sisters. Given that, the tag "protagonists full sister as a heroine" can't be correct.
