11mm is the average Iris length
1px=0.05 cm
341px=17.05 cm =face length
245px=12.25 cm = Distance between Ryueen's leg and Hosen face when he was in the motion of kicking Hosen
Reasoning for putting the line (The line between Hosen face and ryueen kick) there is due to how Ryueen's legs is position in the second page which leads me to Assume that the Black part of his kick is his knee and the white part is his leg rather than it being a speed line for his foot and In panel 2 its shown that Hosen grip on Ryueen's leg is incredible close to his knee. Panel 1 and Panel 2
291px=17.05cm (His Face length we found from the previous panel)
1px=0.05859106529 cm (1px in this Panel)
Purple line=28px =1.64054982812 cm
red line=86px = 5.03883161494 cm
Distance between Ryueen's leg and hosen face when the leg is caught =5.3 cm
Distance between Ryueen's leg and Hosen's face when Hosen realise Ryueen kick was coming towards him =12.25 cm
12.25-5.3=6.95cm (Distance ryueen leg travelled) =0.0695 meters
60mph=26.8224 m/s ( Absolute Lowball of Ryueen's kicking speed) The average kicking speed of someone with no combat or sports training is 60mph while trained fighters and soccer players can kick at 80mph
0.00259111787 seconds (Timeframe)
58px=17.05 cm (Hosen face in the full body panel) (Using this new panel is needed to find how much distance did Hosen arm travel to block Ryueen's attacks) (Hosen used the arm furthest from Ryueen since his closer arm was chocking Ibuki, refer to panel 2 to see it)
1px=0.29396551724 cm
The kick had been 5.3cm away from Hosen's face so to find how much distance he actually covered I'll have to find long is 5.3cm in px is in the full body panel
5.3/0.29396551724 =18.0293255133 (So the kick was 18 pixels away hosen face in the coloured panel)
The discrepancy between the two panels is due to the fact that I can't edit old lines (The coloured lines in the panels) once I create a new lines. So to be accurate I redo the lines since the lines have to connect with one another and go past the other)
Blue line=294px = 86.4258620686 cm
Purple line=95px =27.9267241378 cm
Hosen arm moved 90.83 cm

Low Midball
60mph is the kicking speed of the average person who has no combat or sports training and 80mph is the kicking speed of pro fighters
Ryueen's kicking speed should be somewhere in between the two of those speeds since his an Infamous deliquent, it was stated that his fighting experience was many times that of the average criminal, He was able to beat Ishizaki who was said to have terrorized the people in his town, He tamed the other students in his class through violence, these other students constituting off athletes or other deliquents and he was stated by Ayanokoji to be a decent fighter
