Wow, I ended up diving deep into this because I love tracking long-running shows — 'Shinbi House' has six main seasons as of mid-2024, plus a bunch of specials and spin-off shorts that sometimes feel like mini-seasons on their own.
The show splits its storytelling into big seasonal arcs with recurring characters, but it's also notorious for dropping extra content: holiday specials, web episodes, and even crossover-ish shorts that expand the lore. If you just count the core televised seasons, though, six is the safe tally. Between each season there are often little animated bites or tie-in music videos that can be easy to miss unless you follow the official channels.
For someone who re-watches episodes for favorite ghost designs and soundtrack bits, those extras are a big part of the fun — but if you only want the main continuity, focus on the six seasons and you’ll catch the main story beats. I still get a kick out of spotting callbacks whenever I revisit them.
