I just hope this manga will end after this arc, it overstayed its welcome, it jumped the shark way too much, if someone that only watched the anime was introduced to this arc they would drop it in the trash.
It should have kept being a stupid serie with its feet on the ground.
You clearly don't understand the power that a monthly series have after 170 chapters.
Yes,that's 14
YEARS to reach this point,and they've only just finished their first summer break(second for most,since most are second years),jumping the shark was EXACTLY what they did,even with the bits they've animated.
We welcome an alien plot with open arms as much as we welcome Indiana Motherhumping Jones who looks just like his father finding a crystal skull that acivates due to a babana shaped snack from Tokyo,may D-Frag last forever!
But also,give us Hell,give us high water,both even,give us more seasons of the animated series!
