Ryūken Senju either through real flight through the technique or movement on the surface of earth, can maintain speed and reflexes far in excess to that of even most superhumans. His prowess highly outmatches that of Hotaru easily. He has also demonstarted that he is fast enough to comfortably catch bullets and other propelled projectiles. He has been seen to fly at Mach 10 speeds (7690 mph) in the Earth's atmosphere. Speeds faster than this cause great environmental damage and are avoided unless absolutely necessary. However, he has been seen to be capable of travelling in space as well, though he mentions that his experimentation came in handy to achieve that particular feat. He can therefore fly at speeds exceeding the escape velocity of earth (7 miles per second) under his own power. W
