While MC want to be a "Shinobi" because of Sakuya, but the reasoning and resolve for it are too bland to me. though I can get it that you don't wanna go back being afraid of the dark and all again with Sakuya gone. At the very least, put some serious dialogue that the readers can empathize with. Not some generic bland characters, forced gags with unnecessary forced fan services(I know it's Ecchi genre, but still put it in the right spots, not all the time). Plus, the forced hazing part totally ruined the chapter and the great impression I felt when I read the first chapter.
The whole chapter look like watching key points. Although the key points are important, without the subtle yet necessary inbetween(s) to supplement the story, it's just pointless to look at.
