Erinne's manga / #Action(18)

This is the last chapter I'm crying T.T I'm gonna miss Senku gosh I love this manga/anime so much can't wait for S3 and Ryusui's animation

Took me so long to finished this one, I'm not particular with the plot but it doesn't make sense to me. What was the uke's actual personality? What happened to the Caelum after war?. And I don't know where the focus are. The relationship of those two is not written well. It was still worth a shot reading if your into Gangster type stories
