Fire Emblem Warriors: Three Hopes has many returning faces, some of which are your enemies. The main protagonist of Fire Emblem: Three Houses, Byleth, and legendary knight Jeralt are a few foes you face off against, but is there any way to recruit them to your side in Fire Emblem Warriors: Three Hopes?
How to get Byleth/Jeralt in Fire Emblem Warriors: Three Hopes
The answer is yes. You can recruit Byleth and Jeralt, however, it is entirely missable, as the game more or less tricks you into bypassing your only opportunity to get the duo.
In Chapter 10, when this message appears, “Your actions in this battle will greatly impact the outcome of the story,” is the mission where you can recruit Byleth and Jeralt. In this mission, you have to escort your House leader, in our case Edelgard across the map to meet Byleth and then retreat to where you started. Play the mission, and complete all side quests until the main mission says Avoid engaging Byleth and help Edelgard retreat safely. Replace Eldelgard with your House leader.
But do nothing but this instruction. Follow it 100%. A side mission will appear not long after this main mission starts when Arvalls tells you to Face and defeat Byleth. Ignore this. If you defeat Byleth, you have lost your one chance to recruit Byleth and Jeralt.
Before you reach the mission’s starting point with your House leader, you want to place a very powerful unit of yours in the top left corner—as shown in the image below.

You do this because when you get back to the start, a new unit appears in the top left and corner, and you have to race Byleth up there to defeat this new foe. But we planned ahead, switch back to your placed unit, defeat the enemy, and Jeralt’s Mercenaries will surrender, and you get both Byleth and Jeralt as recruits. They are both mighty fighters and will fit perfectly into your team.
