Reborn
I love how virtually every reaction from Tsuna was "WHAT, WAH, WHAT? WHA!!?" Bringing it all back to 7³ policy (Tri-ni-set) was actually nice and I actually did enjoy the discussion. The walk down memory lane was cool, so many favorite moments, and having watched the entirety of the anime recently was fun to see those moments again. Expected Tsuna response, but thats what I love about him.
I think of the manga in WSJ, Reborn would be my all time second favorite after Naruto. Reborn is always consistent and I love Amano's designs, especially upclose.
It also doesnt feel right reading it when they don't say Tsunayoshi-kun...
