Don't Die! The Law of Tenko Ueki no hôsoku : Season 1 Episode 29

Tenko is grateful to Ueki. He has given him friendship, a purpose and treasured memories. But Tenko has a secret: if he raises Ueki up to nine stars, Tenko will die. Tenko knows that if he tells Ueki this he will refuse to reach the nine-star level. However, Tenko knows that Ueki has to get stronger to face his opponents. Unsure about what to do, Tenko decides to give his life for Ueki's quest to become stronger. After all, it was the first time in a long while that Tenko has felt needed and he appreciates it so much. When Mori finds out about this secret, she rushes off to stop Tenko from raising Ueki's level, but it is too late: Ueki is already inside of the awakening organ and he can't hear Mori from the outside. Will Ueki lose another precious friend in the name of this heavenly tournament?
