Sasuke Retsuden: The Uchiha Descendants and the Heavenly Stardust
Kail ran into Lyla while she was chasing a group of thieves, who had stolen a ring from her. The man who was with Lyla chased and stopped the thieves. Noticing his usage of ninjutsu, Kail came to the conclusion the man was a shinobi. As a thank you for helping her get her ring back, Kail brought Sasuke to her home to answer his question regarding the Sage of Six Paths' history with the country, not before attempting to get him to marry Lyla before he revealed he had a family.
