Pity they didn't use the original theme song. Now the Onegai tradition has been restored...I guess *DISCLAIMER* I don't own any copyright of the clips or the song. They belong to their rightful owners.
All of Go Nagai's major properties got revivals in some way to commemorate 50 years in the industry. Mazinger got a movie, Devilman had the show on Netflix, and Cutie Honey got this.
I first watch this video(without knowing its from Flash version), so watched the actual intro have me confused It suck that they can't get the song copyright, cuz the artstyle look fine and fit the F version(the one used here) like a glove
