Tears to Tiara

This port also contained several enhancements and additional scenarios including new character designs and changed the original 2D gameplay to 3D. A side story for the PlayStation 3 port titled Tears to Tiara Anecdotes: The Secret of Avalon (ティアーズ・トゥ・ティアラ外伝 アヴァロンの謎, Tiāzu tu Tiara Gaiden: Avaron no Nazo) was released on September 17, 2009 and a sequel titled Tears to Tiara II: Heir of the Overlord (ティアーズ・トゥ・ティアラII 覇王の末裔, Tiāzu tu Tiara II: Haō no Matsuei) was released on October 31, 2013.

The game draws heavily from Welsh, Celt, Christian and Roman mythology, with characters named Arawn, Arthur, Epona, Llŷr, Morgan, Pwyll, Rhiannon, and Taliesin. Set in a Late Antiquity–inspired fantasy setting, story starts on an island, Erin (or Hibernia, as shown on an in-game map), on the west border of the Holy Empire. The prologue is centered around the precognition-gifted priestess of the Gael tribe, Rhiannon. She is kidnapped by a rogue priest of the Holy Empire, Drwc, to be used as a sacrifice in a ritual meant to resurrect the Demon King Arawn and put Drwc in his favor. As a response the Gael people burn their village and swear to bring Rhiannon back or exact revenge on the Empire. In the middle of the ritual, as the Gael people attack Drwc's soldiers, Arawn is resurrected and offered Rhiannon. At this point, he kills Drwc, frees Rhiannon, and proclaims no intention of wreaking the havoc which the legends attributed to him. Instead, he shows interest in Rhinannon's brother Arthur, the First Warrior of his tribe. Rhiannon, on the other hand, falls in love with Arawn, and by declaring her decision to marry him, makes him the chieftain of the Gael tribe (her and Arthur's father was the previous chieftain, but Arthur could not assume the title due to being the First Warrior). As the prologue ends, the point of view is switched from Rhiannon to Arawn, revealing him to be the protagonist of the game, and the story continues with the exodus of Gael tribe to the neighboring island of Albion (or Insula Britannica, as shown on an in-game map) in hope of eluding the Empire.

Tears to Tiara was first released as an adult game on April 28, 2005, by Aquaplus’ adult game division Leaf for the Windows platform.
