This is Love Adventure. A stunning and dazzling look at what a Japanese cartoon intro might have been like, if video game graphics had never progressed far past Atari.
I hope you enjoy it.
Music in the animation by the amazing Lacuna Coil, song title: Senzafine
For those that actually tried to guess what show this was based on, someone has indeed gotten it right. I was very surprised. They declined to have their name or a link put at the front of the animation like I offered.
Their guess "The animation is not based on any particular anime intro and is mostly if not all original." Which is sadly true. It's not based on any particular show. Which sort of makes me a liar and a horrible person. Sorry to anyone who wanted to watch the show it's based on! Please still like the animation. Do not hate me.
