Subete ga F ni Naru
Mobile Suit Gundam: Iron Blooded Orphans
One Punch Man
Young Black Jack
The bolded are my top five favourite (in no particular order) but I should point out that none of them come close to how much I'm enjoying the OVA series Mobile Suit Gundam: The Origins which is in a league of its own.
LOOOOOOOL finally someone raided my favorites list How does it feel, flavory one? You got NTR'ed! Seeing your waifu on my list has devastated you beyond description, now I'm going to go on skype and tell everyone your waifu's are mine
