This is my character Lady Hanako, the Sensei of Jo, Kimi, Jasper, Tina, Micheal, Darcy, Alex, and Mandy. When she was still a young adult, she used to train with Wu, Garmadon, and Misako at the monastery. She was having a great deal of difficulty learning Spinjitzu but didn't really mind since she was staring to fall in love with Wu. She never said anything though because she knew he had a crush Misako, and rather than tell him and risk him denyin her she kept to herself. Days later she still had no progression in learning Spinjitzu and had noticed that Wu was now in love with Misako. She had realized she didn't have a place at the monastery anymore and in the night she left a note and left. In the morning Wu found the note, it saying:
'I do not believe I am destined to learn Spinjitzu here with you and your brother, Wu. I have decided that I should find my place elsewhere. Perhaps one day we may cross paths again, but until then this is farewell.
He never heard from her again, atleast not until he and his students come across her monastery one day.
