When is proper MC coming in? All this scheming and whatnot is not really that interesting after that cliff and some very interesting side stories.

so that is Reens replacement? Dude seems stable enough to make it but it is doubtful that there is nothing planned or though about taking her back. Sure that sounds impossible but Eren is not the one to bend.

Story and world are great. Part with tower and challenges was kinda boring until sage. If it was shorter it would not be as annoying, but that's just me. Eren and his inner turmoil plus relationships did wonders to negate aftertaste of boring tower part. Overall I'd say part one was 4 out 5, while part two was 3.5/5. Still makes story one of the best published on web novel overall. So great job!
