Startica is the Summer Festival on Jurai. Many years ago, Tenchis grandfather Yosho met a young girl during Startica, and just as their relationship blossomed, they were attacked by the Jurai Palace, who revealed that the girl was Yuzuha--the demon of Jurai! Wounded by the attack, Yuzuha fled, but many years late her feelings of betrayal led her to plan her revenge by taking Yoshos only grandson--Tenchi! On a hot summer day, a fetching young girl named Mayuka appears to Tenchi, calling him Daddy! Jealousy and envy follow as Ryoko and Ayeka battle for Tenchis attention with an apparently new rival. Who could the mother be?! Sasami befriends Mayuka as they compare Earths Christmas and Jurais Startica celebrations and Mayuka is welcomed into the Masaki household. However, Mayuka is just a puppet of the Jurai Demon and its Yuzuhas plan to bring Tenchi to her Nightmare World, completing her revenge! Will Tenchi be able to resist Mayukas love? Can Sasami convince Mayuka to change? Its a battle for Mayuka as she chooses between her parents, Tenchi and Yuzuha! To be the Daughter of Light or the Daughter of Darkness! <br />
