Update 2.5 added two Berserk-inspired units to Anime Expeditions, and neither one comes from a banner. Guts is a raid drop, while Griffith starts as a free base unit handed out by an NPC and only becomes useful after a long farm. The paths barely overlap, so it helps to treat them as two separate jobs.
Quick answer: Clear Snowy Castle Raid Act 3 on Hard Mode to get Guts (Iron Wolf), and talk to the Broken Falcon NPC in Crimson Shore to claim Griffith, then farm 150 Redeemed or Sacrificed Souls in Eclipsed Infinite to evolve him.
Where both units come from
| Unit | Source | Evolution requirement |
|---|---|---|
| Guts (Iron Wolf) | Snowy Castle Raid, Act 3, Hard Mode | Demonslayer equipment from Snowy Castle Raid Act 1 |
| Griffith (Broken Falcon) | Broken Falcon NPC in Crimson Shore story map | 150 Redeemed Souls or 150 Sacrificed Souls |
Guts is the faster of the two if your account can already survive Hard Mode raids. Griffith is free on day one but locked behind a grind, so most players start his quest early and chip away at it between raid attempts.
How to get Guts (Iron Wolf) from Snowy Castle Raid
How to claim Griffith (Broken Falcon) in Crimson Shore

Pick your evolution path before you start farming
Griffith has two final forms, and the soul type you collect decides which one you get. Committing to a single meter is the fastest route, since splitting your runs between the two just doubles the work.
| Soul type | Item bought from the NPC | Resulting form |
|---|---|---|
| 150 Redeemed Souls | Cursed Egg | Silver Falcon |
| 150 Sacrificed Souls | Eclipse Shard | 5th God Hand |
Farming Redeemed and Sacrificed Souls in Eclipsed Infinite
Souls only come from Eclipsed Infinite, a separate mode marked with an eclipse icon on the story map selection screen. School Grounds is a common pick, but any stage carrying the icon works the same way.



Note: at 10 souls per completed run, 150 works out to roughly 15 clears. Eclipsed Infinite is not a short mode, so plan for several sessions rather than a single sitting.
How to confirm the quest worked
The victory screen at the end of an Eclipsed Infinite run lists your souls alongside the rest of the stage rewards. If that line is missing, the meter never locked in, which usually means the card picks were split between Redemption and Sacrifice across the run.

Once your total hits 150, return to the Broken Falcon NPC in Crimson Shore and exchange them. Redeemed Souls buy the Cursed Egg and Sacrificed Souls buy the Eclipse Shard, and the item then feeds into the evolve menu for Broken Falcon. The quest text updates when the exchange goes through.
Units that make both grinds shorter
Snowy Castle on Hard and the late waves of Eclipsed Infinite both punish underpowered rosters. Sinbad, Judar, and Itachi remain the reliable picks for clearing them, and pairing one of those with a farm unit keeps your economy going long enough to reach the final boss.
Neither Guts nor Griffith needs to be pulled, which makes them worth chasing even on a modest account. The gate is time, not luck, and the main decision you actually make is which Falcon form you want at the end of it.
