Detailed official description:

"This epic collaboration brings fan-favorite characters, such as Saitama, Terrible Tornado, and Boros. Iconic characters from "One-Punch Man" bring their own fast-paced, hyper-destructive combat abilities that sync perfectly with Crystal of Atlan's unique air combo system, delivering an exciting and satisfying gameplay experience.

Event: "Path to Hero" – Wear Saitama's Skin: Players join the crossover event to take on Boros, the powerful Dominator of the Universe, in an exclusive boss battle. Defeat Boros to earn the coveted Mark of the Dominator, redeemable for rare crossover rewards. Meanwhile, the Path to Hero event lets you unlock your Master’s License, gain exclusive avatar frames and titles, and obtain the highly anticipated Saitama transformation item.

Exclusive Collaboration Pets and Mounts Arrive: Pet Terrible Tornado joins as a powerful S-grade support pet, using her psychic abilities to dominate the battlefield by crushing foes with flying steel and stone. Alongside her, two brand-new collaboration mount paints — "Sky Knight - Genos α" and "Windride Skateboard - Hellish Blizzard β", are here to amp up your rides!

The Brand New Class Mystrix Debuts on July 10: Mystrix is the newest subclass of Musketeer — a master of magitech weaponry who combines graceful precision with explosive firepower. In battle, she transforms her Weapon Case into a variety of weapons, including a Shotgun, Sniper Rifle, Floating Cannons, and even a Motorcycle, allowing for versatile offense and agile movement. As she switches weapons and deals damage, she builds up Weapon Charge to unleash Gunfire – Bloom, converting her Weapon Case into a devastating Charged Pistol that delivers a massive burst of damage." ²
