This chapter was a little bit corny, but dammit, it felt like the Beelzebub I love again. Kanzaki's complaint about panel size was freaking great. This is certainly an unusual training arc, what with a progress report and a bunch more plot stuck in the middle of it all. It's refreshing to see the standard training arc formula mixed up a bit.
I am definitely looking forward to see where this goes from here.
I was laughing so hard about that xD. This is going be one funny war I can already see it.
