The teams behind the international release of Heaven Burns Red — WFS Inc, KEY / VisualArts and YoStar – have announced a special in-game event to mark the RPG’s 100-day anniversary. Running from now until 20 March 2025, the event introduces Chapter 4 – Part 2, alongside a new side-story event titled Thou Art This Summer’s Fairy, A Sight I Shall Record in My Eyes. Players can also look forward to new Memorias, login rewards, and recruitment banners.
During the anniversary celebration, players can participate in the side-story event, which follows Squad 31-A and Yuina Shirakawa as they travel back in time to a summer resort—one of the early sites of the Cancer invasion. The team aims to alter history while also making the most of their time at the resort.
To commemorate the occasion, players will receive a 100-Day Celebration SS-Guaranteed Ticket through a daily login bonus. Collecting 10 tickets grants a 10-pull in the SS-Guaranteed 100-Day Release Celebration Recruitment banner, ensuring an SS Memoria. Additional login rewards include up to 50 Lifestones, upgrade materials, and Quartz.

Eight new Memorias will be introduced, including six SS Memorias and two S Memorias. Among them, Yuina Shirakawa and Tama Kunimi will receive swimsuit-themed SS Memorias. Yuina Shirakawa, a dark-element T1 unit, specializes in AoE attacks that enhance overall team strength. Meanwhile, Tsukasa Tojo and Karen Asakura will debut Secret Service-themed Memorias, with Tsukasa Tojo, a light-element T1 unit, bringing significant squad enhancements.
