Okay, nerd moment: As a long time manga reader, there's some amazing visual/situational jokes that happen that most will miss during Millis's introduction.
1.) A fantastic visual joke on pages 35 and 36. When Reid and Millis are going back and forth on the differences of their hometowns, on the final panel of page 35, Millis breaks character model in a Bocchi-esque type of visual joke. However, then when she tries to pose a retort on the final panel of page 36, Reid also has a similar gag. Repeating the same style with the same composition is a fantastic way to bring humor.
2.) A wonderful reaction shared by Reid and Elria is on pages 38 and 39. When Millis pounces at Reid in a final, silly attempt at making a country bumpkin friend, his tiny, in-panel reaction is a small, "Woah". Then, the next page when Elria is the receiving end of Millis's boundless energy with the handshake, Elria ALSO responds with a small, "Woah". Just a very tiny nod that they are so similar that they are bound to be together.
Okay, nerding done. It's just little moments like that that often get missed that separate a good read from a great one. Wanted even one more person to read this and appreciate them.
Edit: Also being able to see Millis's legs in panel 3 of page 26 is fantastic attention to detail.
