This blog has the quotes for the feats.
Zero's fist[]
| “ |
Zero swung his giant fist toward Akuto again. —Kh! Akuto deflected it and flew back to escape. He waited for an opening at a distance. Zero’s fists used a combination attack that did not befit his giant form. Mana was meant to be used by a human body. That meant mana was most efficiently used by someone with two arms and two legs like a human. Even if he was a machine, Zero’s fighting style resembled martial arts and he did a splendid job of making efficient attacks using his two arms. He swung his long arms and legs and the hands and feet at the end easily broke the sound barrier. His fists compressed the air and a conical cloud of steam exploded out around the fists to add power to the attacks. But the timing and openings of his attacks were essentially the same as in martial arts. —In that case, I have no choice but to answer in kind! “Ohhhhh!" roared Akuto. He clenched his fist and shot forward. His opponent was ten times his height, so the difference was greater than that between and adult and a child. |

| ~ Volume 9 |
Zero is 10 times larger than Akuto.
First let's figure out the Volume of Zero's leg then. According to this (page 44+) the mean volume of a leg is 9.955 liters = 0.009955 m^3
In that case the volume of Zero's leg should be around 10^3 times higher than that, so 9.955 m^3.
With Zero being a futuristic I will assume he is made from aluminium, as an example for a lightweight metal.
Density of aluminium is 2700 kg/m^3.
With that the mass of Zero's leg is 2700 * 9.955 = 26878.5 kg
His leg movement is stated to break the sound barrier, so we can do an KE calc using the speed of sound, which is 343 m/s.
0.5*26878.5*(343)^2 = 1.58111432325e9 J

Act 5 Akuto lifts Genkaku[]
Time to quantify lifting strength.
The aircraft is stated to be 350 meter long. This is the biggest aircraft I could find.
It is 84m long and weighs 285000 kg.
We will upscale this, meaning we assume the density stays about the same with volume increase.
350/84 = 4.1666666666666667 = Upscale Factor
4.1666666666666667^3 *285000 = 2.0616319444444444939236e7 kg
Class M Lifting Strength
The energy needed to lift such an airplane by, say, 1 meter would be
m*g*h = 2.0616319444444444939236e7 * 9.81* 1 = 2.022e8 J

Act 1 Akuto blows up a classroom[]
The notable thing here is that we are given an overpressure.
5 kilograms per square centimeter = 49.05 N/cm^2 = 4.905 bar
Using the formula P= 6784*W/R^3+93*sqr[W/R^3] from here we can solve this to tons of TNT.
For that we need to guess R. Looking at the first chapter of the manga the classroom has about 6 rows of tables.
Female student height = red line = 158 cm = 101 px
1 px = 1.5643564356435644 cm
1 row = green line = 95 px = 148.613861386138618 cm
So 6 rows make the classroom about 8.92 m wide and as such the radius of the explosion should be around 4.46 m = R.
Setting in our known values we get the equation:
4.905 = 6784*W/(4.46)^3+93*sqr[W/(4.46)^3]
=> W = 0.0387 Tons of Tnt
