Eclipse Knight Saga ~Touchable Princess Knight Mary~

Eclipse Knight Saga is an adult visual role-playing game that follows Princess Mary, the kingdom’s second princess, after she is captured and humiliated by mercenaries brought in by a neighboring country. Expect bold anime-style visuals, tentacle-themed content, and mature story elements. Throughout the experience, you’ll face high-stakes choices that shape the rescue attempt and the fate of the characters around her—tested by emotional strain and moral pressure. The game also delivers a detailed character lineup and a wide character system, giving it the feel of a harem-style mercenary recruitment adventure.

Awesome Storyline

Princess Mary, the second princess of the royal family, is taken prisoner by mercenaries employed by a foreign power. Unable to resist, she suffers humiliating tentacle-themed ordeals—while the kingdom’s rescue unit closes in. This royal-themed RPG is split into two parts:

• Part 1: the rescue narrative focused on getting Mary back.
• Part 2: the story shifts to Mary herself and her continuing journey.

(See the included instructions text for details on how to skip the prologue.)

Fantastic Features

This full adult role-playing experience includes eight chapters—seven prologues plus one main chapter. The prologue content functions as a short, prequel-style setup for the main plot, while the core story continues the central narrative and adds side activities such as recruiting companions and exploring erotic scenes across multiple locations.

The game features:

• Over 30 companion characters



• Over 80 base CGs and erotic scenes, including tentacle-themed content
• A strong focus on interspecies sexual acts, such as mechanical sex, instrumental torture, futanari, group scenes, tickling, milking, and more

Other Features

Beyond the main plot, you’ll also find part-time activities like working at a bar or caring for pets, along with erotic events involving companion characters. It is possible to finish the game without raising your corruption/erotic attribute, but doing so will block the recruitment of certain characters and can create difficulties in other parts of the adventure.

Excellent Performance

Princess Mary’s Imprisonment Struggle

You take the role of a member of the rescue team, sneaking into a fortress protected by tentacle monsters. Work through environmental puzzles to locate Mary’s cell while staying alert for traps and enemy mercenaries. Every decision you make directly impacts her survival—will you choose stealth, or take the fight head-on?

Mary’s Retribution as the Protagonist

After Mary is freed, she becomes a vengeful warrior empowered by tentacle magic. She can command hybrid creatures, manipulate hostile forces, and deliver brutal revenge. The story explores trauma, recovery, and the awakening of dangerous power—while your choices influence the direction of alliances and the eventual outcome.

Dynamic World Building

The setting is a decaying kingdom scarred by the abyss’s horrors, reflecting Mary’s fractured inner world. Travel through cursed forests, navigate labyrinth-like dungeons, and explore a floating castle where light and darkness fight an endless war.

Helpful Tips

Tactical Rescue Missions

• Lead a squad of knights through procedurally generated dungeons.
• Use the terrain to your advantage and deploy siege weapons.
• Look for enemy patrol routes to avoid unnecessary losses.

Warning: failure can be brutal—hostages may be executed, and Mary’s health can deteriorate.

Hybrid Combat System

• Switch between melee combat (sword fighting) and magic (tentacle summoning).
• Successful combos can deal extra damage.



• Parry attacks and counter using tentacles.

Boss fights require planning—focus on enemy weaknesses, such as glowing energy cores.

Reputation and Morality System

How NPCs judge you depends on your choices. Saving civilians may build alliances. Raiding villages can secure resources, while betraying allies can offer short-term rewards. Increasing “Darkness” unlocks harsher tentacle abilities, but it can also alienate allies.
