Project No.9 just dropped the official trailer for Seihantai na Kimi to Boku Season 2 (*You and I Are Polar Opposites* / We're Polar Opposites), the continuation of the opposites-attract shōjo adaptation that quietly built one of Spring 2025's most loyal audiences.
Quick answer
Seihantai na Kimi to Boku Season 2 (*You and I Are Polar Opposites Season 2*) — the continuation of Project No.9's adaptation of Kocha Agasawa's manga — released its official trailer on May 25, 2026, confirming the second cour and previewing the next arc's emotional pivot. The original 2025 cour landed in the upper-mid tier of SenpaiRanks's romance ranking; Season 2 enters with a pre-confirmed voter base inherited from the first run.
What the trailer signals
The trailer is structurally tight — cold open on the existing dynamic between Suzuki and Tani, transition to the new academic-year setup that the manga's middle arc revolves around, music drop that returns the Season 1 opening artist (a deliberate continuity move).
Project No.9 keeps the same direction + character design team. The art style holds — the soft-line shōjo register that made Season 1 a sleeper hit didn't get sanded down for a wider audience this cour. That's a small but important signal that the production committee trusts the audience that already exists rather than chasing a bigger one.
How Season 1 ranks on SenpaiRanks
The 2025 cour data on SenpaiRanks:
- Upper-mid tier of the Spring 2025 romance ranking
- Per-episode community scores held in the mid-3 to low-4 range across the cour
- Voter base grew steadily — most properties peak at episode 1 and decline; this one built
- One of the higher female-skewed shōjo signals of the 2025 cohort
That builder-not-decliner shape is what justifies a Season 2 the way SenpaiRanks's data tells the story.
Premiere window
The trailer confirms a Fall 2026 premiere window without a specific date. Expect the date + episode count to drop in late July or early August, alongside the OP/ED artist confirmation (likely the same artist from Season 1 based on the music-cut callback).
