Heartbond Keys & Training

Heartbond Keys unlock deeper acquaintance / Lust Sanctuary beats. The 18 August and 25 August patches handed out a wave of keys from new swimsuit and named-skin stories.

• 18 August keys (after reading the new acquaintance story): Searing Heatwaves · Guinevere, Refreshing Blue · Galahad, Blooms Rippling · Merlin.
• 25 August keys: Star-chanting Enchanting Dance · Galahad, Paladin Order Chief · Morgause, Fleeting Light Ruyue, Scarlet Wake Duchess Guinevere, Queen of the Sea of Lust Morgan le Fay, Gluttonous Dragon Heart Xia, Eternal Abyssal Bond Hayla, Glimmering Thunderoar · Michael, Fall of Emberhue · Gabriel.
• Download milestones also grant keys (e.g. cumulative day-7 on 4M / 5M login tracks). Read the live Event Period table — do not invent counts from truncated Steam blurbs.
• Training Mode: playable saints raise affinity for combat stats and extra voicelines. Merlin (7 July), Pure Jade Morgause (30 June window), Paladin Order Chief Morgause (25 August), plus earlier Galahad training.
• Lust Unleashed achievements track Absolute Obedience steps per saint. Clear them when you open a new Training Mode face.
• Keys are account-bound story unlocks, not a separate gacha currency. If a story is greyed out, finish the prior acquaintance chapter first.

Training Mode and Heartbond Keys feed Lust Sanctuary power. Do not skip the free story reads after a patch day.

The Lust Sanctuary (Divine Desire) is the King's private hall with the Round Table — adult scenes and combat power in one loop.

• Official line: a private hall reserved for the King and the Round Table saints — fully 3D, theatre-grade, seamless 360掳 camera.
• 360掳 Director Mode with cinematic auto-cam and Japanese full voice.
• Live costume swap without leaving the scene. Attire Summon (July) added selectable 12-piece pools that do not duplicate until complete.
• Ambience presets: petal rain, autumn leaves, enchanted forest.
• Training Mode saints (Merlin, Pure Jade Morgause, others) raise affinity for stats and extra voicelines.
• Lust Unleashed achievements track Absolute Obedience, affinity steps, and sanctuary encounters per saint.
• Outfit banners use Attire / Meiyang tickets. Unclaimed limited looks wait for a rerun.

Story cores, permanent SR, and recent pickup skins. Full profiles live on the Holy Maidens hub.

• Executor — Your vessel of Arthur. Always in the party. Fine early, outscaled later.
• Merlin — Sage support / control. Training Mode playable saint as of the July 7 patch. Top-tier sustain.
• Guinevere — Scarlet Knight vice-captain, story DPS/support. Scarlet Wake Duchess was a July limited skin. Searing Heatwaves (瀵稿鐑氮, CRIT Rate +1%) is the Tidefire pickup through ~1 September 2026.
• Morgause — Acting Lord of Camelot, story + gacha tank. Pure Jade Devout Wish (CRIT DMG) ran 30 June —21 July. Paladin Order Chief acquaintance story + Training Mode unlocked on 25 August.
• Galahad — Gormagon Port manager, story DPS. School Crush is a paid Lust Sanctuary set. Refreshing Blue swimsuit and Star-chanting Enchanting Dance both grant Heartbond Keys from acquaintance stories.
• Michael (Glimmering Thunderoar) — Half-year SR, now in the permanent Divine Scion pool with CRIT Rate.
• Gabriel — Archangel. Fall of Emberhue (Flame Fallen) was the late-July pickup. Permanent pool member. Heartbond Key from the 25 August acquaintance story.
• Percival — Night Hunter pickup in early July; also in the permanent SR eight.
• Hayla (Eternal Abyssal Bond), Xia (Gluttonous Dragon Heart), Ruyue (Fleeting Light) — all three joined Divine Scion · Permanent on 7 July (0.25% each inside the 1.40% SR band). 25 August acquaintance stories grant Heartbond Keys.
• Morgan le Fay — Queen of the Sea of Lust limited skin; still a niche control pick.
• Bedivere — Explore partner from the Goddess Shop (Avalon Ancient Coins), not a combat Holy Maiden.

Permanent SR band since 7 July: Michael, Hayla, Morgan le Fay, Xia, Ruyue, Morgause, Gabriel, Percival (0.25% each). Pity is 99 for the Divine Scion series and does not carry between pools.
