Looking at the chapters included in the vol 5 of Agravity Boys, Shueisha really milking the volume releases, half is main chapters, other half one shot / extra chapters, so they still have 11 chapters + the epilogue to include in 2 more full volumes, but i guess Agravity Boys fans have more to read
In other news, kinda surprised with the good score of Build King on Amazon, considering the total lack of promotion and terrible rankings, i thought would be bombed like Samurai 8 and it did started with a 1 star but recovered, in sales is now ranked almost tied with C&D which isn't really a good thing but is Amazon, curious to see Shoseki but it will not sell "good" for sure.
