During the 4.4 Special Program, HoYoVerse teased a bit of the Honkai: Star Rail Fate/stay Night new Holy Grail War Sequel event and what we can expect from the new crossover storyline. Now it shared additional details and infographics on HoYoLab that hint at what will happen when Rin Tohsaka and Gilgamesh head to the game. It goes over more of the premise of this part. In the initial Honkai: Star Rail Fate/stay Night crossover event, we saw the Trailblazer summon Saber as a Servant for a Penacony Holy Grail War that also involved Aventurine being paired up with Archer and Boothill with Lancer. Alfalfa Family head Old Oti found the grail in that storyline, held a event that involved the aforementioned characters, Robin, and Lyndon Skott. It tied in both with Penacony history and included Fate references. The 4.4 Special Program is set in Planarcadia, but does involve the Holy Grail from the previous event. During Star Rail Fest, Pearluxe Corp included that item in an exhibition there. Someone stole it, and it seems Rin is the culprit. She’s basically shipwrecked after travels after the Fifth Holy Grail War, took this grail. It uses Wishpower from Planarcadia. Sparxie is also involved in this latest case, according to the HoYoLab update, and a cuneiform tablet was present. An Uruk Cultural Heritage Foundation might also be tied to the case. There’s also an image of Castorice, suggesting she’s involved. Here are all the latest infographics for the new event.
