Tang Shen was a young woman who was married to Hamato Yoshi, and killed by Oroku Saki. Her daughter was Miwa. Tang Shen was loved by both Hamato Yoshi (Splinter) and Oroku Saki (The Shredder). At some point, she married Yoshi and gave birth to their baby daughter, Miwa. A resentful Saki attacked Yoshi in the family's home, and during their battle, Yoshi's house caught fire. While Yoshi survived, Tang Shen did not and Miwa was taken away by The Shredder. After this, Shredder claimed that Yoshi was the cause of her death, although he was the one who slaughtered her accidently when she tried to stop Saki and Yoshi from killing each other. Following her death, Yoshi left Japan and moved to New York City. Her death is possibly the reason that Yoshi bought the turtles in the first place.
