Mistakes of Youth is a webcomic started in 2006, revolving around the adventures of Rets, a "borderline hikikomori" otaku with a penchant for lolicon, Tina, a yaoi/shotacon fan who is inexplicably Rets' best friend, Brad, the shopclerk who is constantly irritated by Rets, and Rets' Japanese internet friend Go.
- Art Evolution: Very subtle, but the characters have gradually become prettier.
- Fetish: Rets' obsession with paedophilia.
- GIS Syndrome: For anime posters and box/manga covers. Often also for televisions.
- Only Sane Man: Poor Brad. His regulars drive him so crazy with their perverted interests that he's willing to like the company of a Naruto fan.
- Take That!: Often implemented. Especially at Hideki Anno's expense.
- Poster-Gallery Bedroom: Rets' room is covered with loli posters from various anime sources.
