Personally, I find it very annoying the every single girl in the group want to be with him part. I mean there are other guys there, not to mention that he is taken. Is he supposed to accept every single girl who likes him because he is mysterious and powerful??
They really haven't stayed with him that long. With Avelia and Tiana, they went through alot of trials and experiences together while all the others, it's quite brief and shallow. Athan literally is always training and leaves to go to other places alot. He also as far as you wrote hasn't shown any interest in them at all. I feel just because a girl loves you, you aren't obligated to love them back. Dudes already happy and satisfied with the two he already has. I just don't see the point.
LivingVoid:not every girl will find him like that. Sen, Linci, and Shiromi have stayed with Athan for long time that;s why. Max harem member wont be that much, after Linci, only 1 or 2 at max.
