Information about how to recruit Hapi in Fire Emblem Three Hopes.
In Fire Emblem Three Houses you could recruit many characters simply by getting specific stats and skills high enough. Once done, they’d be impressed enough to realize that studying under you would suit them better than petty considerations such as life-long friendships, national loyalty, familial duty or even religious conviction.
Unfortunately characters in Fire Emblem Three Hopes aren’t quite as malleable - some characters will join your faction as you progress the Main Questline, usually due to story contrivances entirely outside of your control. The rest, however, must be met in battle and “persuaded” to join you… often by lumping them on the head enough times to realize that they’d be better off defecting than decomposing.
Character Recruitment Strategies
In the case where a character can be persuaded to join you, this “persuasion” effort is achieved via the deployment of a Strategy. When you start a battle in which a character can be recruited you’ll first have to pick from a variety of available [Strategies]. You can find more information about Strategies on their own page, but for the purposes of recruiting characters you’ll be interested in any “Persuade [Character]” Strategies, which you must select prior to the battle to ensure you can utilize said Strategy(ies) during the battle. Deploying Strategies in turn require you to expend Strategy Resources, a currency gained by completing [Side Quests] during the chapter leading up to the Main Quest where enemy characters can be recruited.
During battle, when the character you wish to recruit spawns you must activate the Strategy to persuade them by entering the battle menu before you defeat them. If you defeat them without activating the Strategy - even if you selected it before the battle - they will die and you will not be able to recruit that character for the rest of the playthrough! Once the Strategy has been activated, the area where the Strategy is in effect (usually where the target character spawned) will be surrounded by a purple glow. Merely defeat them in this area and you’ll recruit the character.

During the [Main Quest in Chapter 4], you will be attacking Garreg Mach Monastery and one of the enemy units on the field from the beginning will be Hapi. You can choose the Persuade Hapi Strategy, using 10 Strategy Resources, prior to the battle begins. She will be located in the stronghold towards the southwestern corner of the map. As you approach her with a player-controlled character, you will be given the option to activate the Strategy, by holding the button. Do that, then defeat Hapi to have her join your side.

Having been uprooted from her pseudo-exile/sanctuary in Abyss to fight for the Church of Seiros, she was pressed into service by the Adrestrian Empire when Garreg Mach was conquered. Given that, it’s little surprise that Hapi’s loyalties don’t run deep, and a little bit of “persuasion” will suffice to convince her to join your forces.
During the [Main Quest in Chapter 4] you can deploy the Persuade Hapi Strategy by expending 10 Strategy Resources - a paltry sum, considering you need to clear at least two Side Quests to begin the Main Quest, netting you 20 Strategy Resources along the way. Play through the battle normally and when Rhea gets near the middle of the map, Hapi will spawn and attack. Activate the “Persuade Hapi” Strategy and defeat the girl with dangerous sighs to secure her loyalty… or, well… perhaps “loyalty” is too strong of a word, but she’s yours to command. For now.
