Grand Summoners x Prisma Illya Returns on September 4

The Grand Summoners x Fate/kaleid liner PRISMA☆ILLYA Licht Nameless Girl collaboration is set to return starting September 4 (PDT). According to the official announcement, classic units from the previous collaboration will come back first, with brand-new units promised to follow shortly after.

About This Collaboration

This collaboration first launched globally on December 26, 2025, bringing characters from the Fate/kaleid liner PRISMA☆ILLYA Licht Nameless Girl film into Grand Summoners. At its original release, the collaboration featured several standout perks:

• A guaranteed 5★ Legend on the first roll
• Free choice of classic or summer versions of Illya, Miyu, or Chloe, simply by logging in
• Over 100 free Crossover Summon Tickets obtainable through daily login bonuses and limited-time missions, usable to summon fully voiced characters like Illya, Rin & Luvia, Miyu, Shirou, Chloe, Saber Alter, Sakura, and Bazett (some units only became summonable in later parts of the event)
• Iconic summonable Equips, including Excalibur and Illya's Magical Ruby
• Character skills and Arts that recreate iconic moves from the anime, such as Shirou's Unlimited Blade Works and Saber Alter's Excalibur Morgan

What's Different About This Rerun?

Based on the latest announcement, this rerun follows a pattern seen in previous Grand Summoners collaboration reruns: classic units return first, typically alongside buffs compared to their original versions, before new units join in a later wave. Specific details on exactly what buffs the classic units are getting this time haven't been announced yet, so it's worth waiting for the full details once the event actually kicks off.

What Players Can Prepare

While waiting for the start date, here's what's worth doing now:

• Save up summon currency if you're planning to chase the collaboration's fully voiced units, since completing the full roster previously required a fair number of Crossover Summon Tickets.
• Check your current roster to see if you already own classic units from the original collaboration, since the buffs coming with this rerun could make older units worth using again.
• Watch for follow-up announcements on the new units promised to arrive after the classic units return first.

With a mix of strengthened classic units and new units still to come, this Prisma Illya collaboration rerun is shaping up to be one of the more anticipated events for Grand Summoners players this month.
