The way north #2 went out to battle even though he knew he'd hardly win, unhesitantly, unwaveringly, just as his robotic nature, is just simply pure dramatic and touching. The development is very natural, it came steadily through each chapter, unravel his story piece by piece and finally conclude it with a orchestrated-themed battle.
I would really love to see what the song North#2 was singing in the showdown like, but sadly this is just a manga so no sound, would be great to have an anime but this is way enough feel for me. The author really knows how to create climatic moment, the angle, the arrangement, setting and brightness, everything in single frame was elegantly drawn. And this is only just the beginning of the series.
