Step 3 Interpretation:
I think this text box aims to introduce who “god hand” is, a teacher at the university Saitou is studying at. The only thing I’m unsure is where 春日 comes in. I suspect it might act as last name here. As in the professor is nicknamed 『god hand 春日』. Not 100% sure!
Normally this is where other members come in and give their inputs correct any mistakes made (or confirm that the interpretation is right).
