Blue Protocol: Star Resonance opens Season 4 and confirms a Tensura collab

Blue Protocol: Star Resonance entered Season 4, Lightchase Oath, on October 9, 2026, the same day the game marks its first anniversary. Publisher A Plus Japan also confirmed a future collaboration with the anime That Time I Got Reincarnated as a Slime (Tensura), with no date and no content list.

The notice, carried by Anime News Network, treats the anniversary as a milestone for adventures in Regnus and pairs the new season with the Seabreeze Festival, including limited-time events and rewards. The collab is described only as upcoming: further details are expected on the official site and social channels.

What Season 4 adds

According to A Plus, Lightchase Oath includes:

  • new modes and minigames;
  • the Montegnor Valley map, with NPCs and a new story stretch;
  • new dungeons and Chaotic Realms, built for groups;
  • a revision of the talent and Psychoscope systems.

The notice does not detail season length, item prices, or whether any reward is paid. What is confirmed is the season launch and the existence of these systems, not a full calendar for every mode.

The collab is still only an announcement

The Tensura partnership is a confirmation, not a live event. The text recalls the anime premise — salaryman Satoru Mikami is reborn as the slime Rimuru — and points to the series' official site, but it does not say which characters, mascots or stages will enter the game.

Until the next notice, what changes for current Blue Protocol: Star Resonance players is Season 4. The collab remains an announced next step, without a deadline.

The game site is playbpsr.com. The official X account is @BPSR_Official.
