The latest DanMachi collaboration event has arrived in Isekai:Slow Life, introducing three limited-time heroes from the world of Orario. These characters — Ais Wallenstein, Bell Cranel, and Ryu Lion — bring a fresh wave of abilities, charm, and nostalgia to the slow-paced fantasy world. Each of them comes with unique backgrounds, high initial aptitude, and special traits that make them some of the most exciting additions to the game so far.

This guide breaks down everything you need to know about these crossover heroes — their lore, stats, and why they’re worth adding to your roster before the event ends.

Ais Wallenstein – The Sword Princess

Ais Wallenstein is introduced as an SSR+ Limited adventurer with an Initial Aptitude of 100, making her one of the strongest limited units in the collaboration. Known as the “Sword Princess” in Orario, Ais is a master of swordsmanship and is easily recognizable by her golden hair and stoic demeanor.

In Isekai:Slow Life, Ais plays a Brave role, capable of balancing offense and defense with high versatility. Her presence on the battlefield emphasizes strong single-target damage and durability, making her suitable for both PvE boss battles and competitive scenarios.

In-game Description:“An adventurer from the Otherworld, with blonde hair and golden eyes, she is as beautiful as a god. Mastering sword skills among the best, she is known as the ‘Sword Princess’. However, she’s a bad drinker, always going on a rampage after getting drunk, so don’t let her drink too much. Potato, a specialty of Orario, is her favorite.”

Bell Cranel – The Rabbit Foot

The protagonist of DanMachi, Bell Cranel, joins the Isekai village as an SSR Limited Adventurer with an Initial Aptitude of 75. Nicknamed the “Rabbit Foot,” Bell’s design captures his youthful optimism and unwavering sense of justice. His skills and demeanor make him an excellent support-damage hybrid — ideal for players looking for a balanced unit who can sustain long fights.

Bell’s strengths lie in agility and consistent damage output. He may not have the raw stats of Ais or Ryu, but his reliability and balanced scaling make him an important part of the collaboration lineup.

In-game Description:“Being an adventurer from the Otherworld, he is often regarded as a rabbit because of his white hair and red eyes. He is kind, pure, and has a strong sense of justice — so much that he’d sacrifice himself to help others.”

Ryu Lion – The Gale Wind

The calm and composed Ryu Lion joins as an SSR Limited Elf with an Initial Aptitude of 100. A fan-favorite from the DanMachi universe, Ryu is a former adventurer turned tavern clerk, combining magic, healing, and melee prowess. Her in-game role, Unfettered, highlights her adaptability — capable of dealing magic damage while providing defensive support for allies.

Ryu excels in hybrid playstyles, switching between offensive casting and healing when needed. Her versatility makes her especially valuable for players who prefer balanced teams with sustain and control options.

In-game Description:“A former adventurer from the Otherworld, she is cold in tone and appearance while actually kind in heart. As an elf, she’s born with magic talent, combined with excellent healing ability and melee fighting skills. Versatile as she is, sometimes she’d also show a clumsy side.”

How to Obtain These Characters

These three heroes — Ais Wallenstein, Bell Cranel, and Ryu Lion — were introduced during the DanMachi Collaboration Event, which began on November 1st, 2025. Each is part of a limited-time banner with exclusive drop rates and event missions.

Players can summon them through special event banners using collaboration-specific recruitment tickets or gems. Additional collaboration rewards and event storylines provide lore interactions between the Isekai:Slow Life cast and the DanMachi characters.

Why You Should Recruit Them

While each collaboration event brings unique characters, these three stand out for their strong aptitude and lore connections.

• Ais Wallenstein – High attack growth and perfect for front-line combat.
• Bell Cranel – Reliable all-rounder who fits seamlessly into most team setups.
• Ryu Lion – Provides hybrid magic and healing support, ideal for sustaining long fights.

Their limited-time availability also makes them desirable for collectors, as they may not return for several months after the collaboration ends.

The DanMachi collaboration has given Isekai:Slow Life players a rare opportunity to welcome three beloved heroes into their idyllic world. Ais Wallenstein, Bell Cranel, and Ryu Lion not only bring powerful abilities but also enrich the game’s storytelling with their distinct personalities and origins.

Players are encouraged to summon them while the event lasts, as these characters are likely to become valuable assets both in gameplay and prestige. The crossover successfully bridges two beloved fantasy universes, making it one of the most exciting updates to Isekai:Slow Life to date.
