This series is dark. Possibly the best show of the Heisei era of Kamen Rider, and yet it's name still gets mispronounced. It's name is not "555". It's spelled F-A-I-Z. Pronounced like F-I-Z-E. Also deals with the Greek letter (Circle with line through it). It's characters are not bad either, both with combat and romance aspects. Give this one a try
