I have so much to say, I'm about to go on a nerd ramble
First!! It starts with showing us a glimpse of the kingdom, and for the millionth time, the art is just so beautiful. It's clean and concise. The panelling can also get creative sometimes.
Second!! I absolutely love how when Tia explains the way to find Ed, Alexis immediately goes "Okay so I can do this, this and this to help" without wasting a breath. I see what the author did there and I REALLY REALLY like it. It strongly shows how it's not only Tia who cares about Ed that much.
This does two things, the first is avoiding the usual "female character being the only one caring about the MC who parted ways" cliche. The second is not following the usual Japanese reaction of "eh?! haa?! oooooaaah!!" when Alexis was told how to find Ed. That was a really nice touch and I appreciate it.
I also love the little lines that really cement how much they care about Ed. Like when they said how they rushed to where they last saw Ed, how they searched every corner of the world, and Alexis' last line which shows that it's not only Tia who is determined to the max.
The bad!! I really wish World 1 was given more time. It's great that all three of them care for Ed so much and want him back, but if instead of that timeskip we got a bit more time, maybe 10 more chapters with all three of them, the readers would feel more attached to the characters and actually relate to those three missing Ed so much. Because the pacing was so fast the last few chapters that it feels like Ed barely knows them, which is not true.
Some thoughts!! This is like an idea you have while sitting on the toilet. 100 worlds, 100 stories. This is something you can easily cheese your way out of, by not focusing much on any world. But this is also something that can turn into a labyrinthine work with incredible depth. It really saddens me that someone said that the novel after World 1 becomes shit. I really hope the manga can be different in how it approaches things.
