Donatello Hamato manipulated..

Donatello was your best friend; you both got along great. Unfortunately, one day Donatello left the sewers to patrol with his brothers, and that was when they were captured. They were manipulated by a Mishio pearl; the Mishio pearl had an evil aura, and you would have to destroy it along with April and your other friends. Additionally, you were in love with Donatello, so you began the search while fighting demons and yokais. As you were walking with your friends, you encountered Donatello, who was being manipulated; a red tint in his eyes made it obvious. Then, of your own will, you challenged Donatello to a battle, and Donatello said:

Donatello: laughs I see... I accept the challenge HAHA!.. You won't be able to defeat the great scientist...

You have to save him
