What people sayPublic comments from other sites
AI sentiment analysisAn AI model (claude-session) rates each public comment as very positive / positive / mixed / negative / very negative (scored 9.5 / 8 / 6 / 4 / 2), averages them weighted by confidence, site, length, “helpful” votes and date, then shrinks the result toward a neutral 6 (so a few comments can't inflate it).Calibrated to the site-score scale it is 5.40, and it counts toward the overall score by the number of comments (at most 35%).Only the latest ~40 comments per site are read (plus ~50 posts from each forum's episode threads, which weigh less): a sample, not everything. Excerpts are at most 140 characters and belong to their authors; comments that may contain spoilers are not shown. Comments from Chinese sites appear in an AI translation, with the original one click away. Sentiment labels can be wrong. Updated Oct 7, 2026, 06:36.See the score breakdownSentiment score4.6/10

Very positive
The best of the season and that is the reason "hidden gems" must stay hidden
Negative
Just call yourselves wishy-washy three Either there's really not enough material to end the season in a good spot, or the production is…
Very positive
This has to be one of the more interesting and creative series to come out in a while. Already easy top three for the season out of a few…
Negative
If there's one thing this series knows how to do it's how to blueball the audience.
Very positive
12 minutes-in impression Huh. As expected, this is certainly "a look", but it's actually quite fun so-far. The pacing is radically…
Negative
That was painfully boring. I can't stand watching anything to do with Segami. Even the Futaba segment was overly repetitious. But I still…

Overall score The overall score is not a simple average but a weighted blend:
(w_P·P + w_T·T + v·R) / (w_P + w_T + v)This title: Site scores P = 6.11 (weight 46, 67%); Fan sentiment T = 5.40 (weight 22.4, 33%); Community: No ratings yet (each rating counts as one vote); P: site consensus 5.50 (1,154 votes), shrunk toward the season baseline 6.99 by vote count to 6.11.P is the consensus of site scores (calibrated to one scale), T the sentiment of public comments, R our community's mean. Each part is weighted in “virtual votes”: more votes and comments mean more weight.See the breakdown · Scoring rules in detailOverall score 5.9/10
Score breakdownThe three parts are weighted in “virtual votes”: the more site votes and analyzed comments, the more weight that part gets. Fan sentiment is capped at 35%, and each AniRanking rating counts as one vote. Full rules
- Site scores6.1167%Consensus of 1,154 site votes (calibrated to one scale and shrunk toward the global baseline by vote count)
- Fan sentiment5.4033%60.5 comments, average 3.89 (the sentiment score shown, 4.6, is also shrunk toward neutral), calibrated against comparable titles to 5.40
- CommunityNot counted0%No ratings yet (each rating counts as one vote)
Site scoresThe site consensus is 5.50 (1,154 votes, weighted by site reliability × log of votes); shrunk toward the season baseline 6.99 by vote count, it becomes 6.11. Sites score differently (Bangumi runs low, bilibili high), so each is first calibrated to one scale using titles rated on both it and AniList, then combined; sites with fewer than 100 votes are ignored.
