Calc bububuki 3 (bubuki buranki)

swag-kun shots his bullets but they get repelled so he just bites it

his head is 442 px(0.236
bullet is 23 px (12.28 mm)
https://en.wikipedia.org/wiki/12_mm_caliber
so i'll be using nitro pistol
average nitro pistol speed is 660 m/s
size of his mounth is 71 px (3.8)
he also closed 36px (1.9 cm) of it after opening
now

his head is 587 px
the bullets are 69px
panel lenght is 772px
panel height is 447px
2*atan(tan(70/2 deg))*(772/447)=120.894855 deg 2*atan(69/(772/tan((120.894)/2))) 9.64828862 deg
or about
0.07524 cm
now his head
2*atan(587/(772/tan((120.894)/2)))
71.3554675 deg
0.16435 m
distance crossed is 0.16435-0.07524=0.08911 m
timeframe is 0.08911/660=0.00013501515 seconds
distance his mouth moved in this time is 5.7 cm
0.057/0.00013501515= 422.17484 m/s

matobai shots and things goes boom

6 stores building is 50px (31.255 m)
explosion diameter is 79px (44.3821 m)
r_thermal = Y^0.41 * constant_th
r_blast = Y^0.33 * constant_bl
5000 tons = 476m R air blast, 100% fatalities
22.19105/476=0.04661985
y^0.33=0.04661985
Y=0.000092335
E=0.000092335 x 5000
E=0.461675 tons of tnt

matobai shots at the little girl but a-chan arrives in time to stop the bullet

little girl head is 38px
hand finger is 39.93px
but there is a bit of perspective issue
so let's say it is as big as her head
i'll assume she is 1.5
1.5/6=0.25 m for her head
now let's get the distance
from the bullets and the distance achan moved

matobai head is 41 px (23.6cm)
handy is 7px (25 cm)
a-chan crossed 82 px at least (2.92857 m) given he was outside of the panel
panel height is 133px
panl lenght is 233px
2*atan(tan(70/2 deg))*(233/133) is 122.631579 deg for pov
2*atan(41/(233/tan((122 deg)/2))) 35.2241299 deg
which gives me 0.37171 m till matobai
2*atan(7/(233/tan((122 deg)/2)))
6.20466114 deg
or about 2.3063 meters till handy
putting both together i get
2.3063-0.37171=1.93459 meters between both of them

here we can see achan is 105 px (he should be around 1.60)
2*atan(105/(233/tan((122 deg)/2))=78.2210414 deg
0.98403 meters
1.93459-0.98403= 0.95056 crossed by the bullets
0.95056/660=0.00144024242 seconds
A-chan speed=2.3063/0.00144024242
A-chan speed=1601.32764316 m/s
