Kiryu's first task is to ensure the safety of the children at the Morning Glory Orphanage. You'll need to clear the immediate vicinity of any zombies. The shotgun is excellent for this, but be mindful of its limited range. Use your powerful melee attacks (Square/X) if zombies get too close, as Kiryu is still a formidable hand-to-hand combatant. After clearing the initial wave, you'll be tasked with escorting a few children to a safer location within the orphanage. Protect them from any incoming zombies. If a child takes too much damage, the mission might fail. Stay between the children and the zombies, using your shotgun to create a path. This segment introduces escort missions, which require careful positioning and crowd control.
