User blog:Muhammedmco/Strike The Blood - Natsuki's Leg Stretch

Introduction
Feat in Question.

Calc
Natsuki (The one who dodged the tentacles) doesn't have a canonical height, but in the wiki, she is 26 years old, yet she was in a sleep for 10 years, so her body is at 16 years old, but she looks like she is 13 years old, so i will use the height of a 13 year old female, which is 62.4 inches.

Natsuki's height = 1.58496 m.

She is 116 px.

1.58496/116 = 0.01366344828 m/px.

I will use this scan to find the distance between Kou and the elevator.

Distance between Kou and the elevator = 288 + 99 = 387 px = 5.287754483 meters.

In this scan, Natsuki was standing further from Kou, which was the complete distance that she took.

Distance between Kou and Natsuki = 133 px = 1.817238621 m.

Total distance Natsuki covered = 5.287754483 + 1.817238621 = 7.104993104 meters.

For the timeframe, i will use peak human FPS, which is 220 FPS, since Kou didn't even realize that she was behind him until she talked.

Timeframe = 1/220 second.

Time = 7.104993104/(1/220) = 1563.098483 m/s = Mach 4.557138434402 (Supersonic+)

Conclusion
Natsuki's Leg Stretch = Mach 4.557138434402 (Supersonic+)
