I got sucked into bingeing 'Cautious Hero:
the hero is overpowered but overly cautious' and then hunted down the extra bits like a hobbyist collector, so here’s the lowdown from that rabbit hole. Officially, the anime’s primary TV run is the core 12 episodes, but there are extra pieces that fans often call ‘bonus episodes’ — generally they come as Blu-ray/DVD OVA extras, short chibi/omake segments, and occasional web specials or audio-drama tie-ins. These extras aren’t usually full-length story arcs; they’re more like side jokes, character-focused vignettes, and silly what-if moments that play off the main show’s tone.
If you’re looking specifically, start with the limited-edition home video releases: the Blu-ray/DVD volumes tend to bundle an OVA or short special episode as a selling point. Those OVAs typically feature light,
comedic content — more slice-of-life or parody than serious plot — such as Ristarte getting flustered or Seiya doing his overly cautious training in absurd ways. There are also the short ‘omake’ or chibi segments that sometimes appear on the discs or as extras on official streaming feeds; they run a few minutes each and are great for laughs if you liked the show’s comedic rhythm.
Beyond discs, keep an eye on official channels and retailers: Japanese product pages (like those on CDJapan or Animate) will list bundled OVA episodes in their item descriptions, and streaming services occasionally include “special” listings for web-only shorts. Fans often compile and subtitle these on community sites, so if you don’t own the physical releases you can usually find translated versions floating around. For collectors, the audio drama CDs that tie into the series sometimes expand small moments into mini-stories — not visual episodes, but perfect for deeper character banter. Personally, I love these extras because they scratch the itch for more of the characters without changing the main story’s stakes; they’re exactly the kind of lightweight, goofy payoff you want after a tense fantasy episode.
