In Undertaker Riddle are examples of:
- Ensemble Darkhorse: Dante.
- Foe Yay: Between Riddle and Roen.
- Ho Yay:
- Between Hayato and Riddle. So much it's not even funny!
- Also between Dante and Hiren. Hiren even calls himself Dante's faithful dog.
- Hayato, of course, because of So Beautiful, It's a Curse.
- Hiren too. You can't help wanting to give him a huge hug when you see him.
- The Woobie: Hiren. Specially after knowing his Dark and Troubled Past.
