How to get the True Ending in Phantom Blade Zero

Phantom Blade Zero has three endings, and only the True Ending lets you face the final boss and unlock the "Final Battle" ending plus the "With Heart and Blood" achievement. Getting it requires completing the Secrets at the Heart of the Lake quest, the five Long Pillars in Bloodline Awakening, and all of Quickhand's Requests. Doing so also grants four outfits and the Radiant Heart story item, and lets you start New Game+ with Inanis.
