I love how Naoki creates a strong similarity between "Boy Without a Face" in 20th Century Boys and "The Nameless Monster" in Monster. Both were forgotten just because they don't have a name/face but that doesn't matter for them.
A heartwarming chapter, no matter how many years have passed, the teacher still did not forget the student and even gave him a photo to prove his existence. I'm crying more than I should have ;__:
