To prevent this mishap from happening again. This question of the app will be changed.

How did your Uchiha awaken the Mangekyō Sharingan?

Will be changed to Why.

This is to signify the emotions that triggered the eyes, and the techniques awakened afterwards. Beforehand, the "how" was interpreted by Daz as the experience when they first used their MS.
