Looks like Eiji won't need to use the series cancel card after all.
Miura will certainly be stubborn and try to keep Tanto going, not sure how Shujin will react. Maybe he'll take a break for a while and get his creative juices back, and Mashiro will spend some quality time with Azuki.
As for Hattori, he sure knows how to keep things professional. Though I agree with that editor, he should go for Iwase
