Believe it or not neither Danganronpa and Boku No Hero Academia are my top 1 anime...

Though they are in my top 5 list.

My favorite number one anime isnt that popular (i think, not sure though..).. its the 'A Certain' series.

1. To Aru Majutsu no Index I / A Certain Magical Index I
2. To Aru Majutsu no Index II / A Certain Magical Index II
3. To Aru Kagaku No Railgun / A Certain Scientific Railgun
4. to Aru Kagaku No Railgun S / A Certain Scientific Railgun S
((All are 24 episodes i think and some OVAs... they also have movies))

It was made at 2009 i think? But it has GREAT animation styles, please watch it XD
