Shadow-Dyed ~The Sister Priestess of Aslington~ Shadow-Dyed ~Asu

"The Key to Curing My Little Sister's Succubus Transformation Is—Defeat the Demon Lord!?" In the utterly ordinary border town of Aslington, the protagonist Lloyd and his little sister Torina investigate the truth behind the sealed Demon Lord in order to cure her succubus transformation—a classic RPG where they grow stronger through battle and synthesis while exploring the labyrinth! Except— "Balance day and night! Manage your stamina and magic needs!—Can you satisfy your little sister tonight?" Torina's succubus transformation deepens over time, and her "magic need"—her craving for male essence—grows stronger and stronger. Will her brother (the protagonist) use his limited "stamina" to satisfy his sister's needs, or to conquer the dungeon and save her as quickly as possible? Whatever choice her brother makes, the understanding Torina will surely be accepting. But as her instincts become harder and harder to suppress, the unsatisfied Torina may start doing bold and dangerous things behind the protagonist's back—after all, in the thick night of Aslington, anything can happen. "Whose trace is this...? Whose memory?" Synthesis—a craft the protagonist learned from a witch, far more delicate and refined than alchemy—will surely be a great help in exploration. Beyond that, synthesis can also glimpse the owner's hazy memories through objects; normally it's just a small skill for finding lost items. But lately, the protagonist has begun picking up torn women's clothing and fluid-soaked strands of hair on the streets—and unconsciously uses synthesis on them. What he glimpses are sweet moans that should be utterly unfamiliar, and a voluptuous figure he should never know, twisting her hips and begging for pleasure. Whose memory is that? ...And after each night that passes, will more such obscene, depraved traces be found in Aslington? "Brother... Torina has been trying so hard... so just a little... would that be okay...?"
