I guess it would be understandable not to show Echoes Act 1 in the OP since it was going to be revealed anyway. David Productions had me worried with their 3-episode rendition of the Nijimura’s Arc but thankfully, we don’t need to waste time with the two weakest “fights” in Part 4. This week, we got Tamami Kobayashi and The Lock and next week we similarly got another one-episode fight with Toshizaku Hazemada.
And wow, looking back, Koichi’s development went through a lot faster than I initially thought. Also, as much as I don’t want to complain about the new visuals, I really hope something happens with Koichi’s fat nose.
