I didn't really feel like IV was anime like Apocalypse was. The only thing you could argue is Isabeau admitting she has feelings for the protagonist in the neutral ending, and even than that's mentioned like, once and then never heard from again. IMO, IV's story is underrated. I like that Apocalypse expanded on that world, but yeah some of the characters....yikes.
My bad, I'm purely referrimg to Apocalypse >.<
IV definitely not animu seeing how it basically a reimagining of SMT1 story.
