Tokyo Shinobi Squad: A Shuriken tries to pin a Xenophobe to a Wall; it Fails

Premise

No wait, sorry. I got that wrong.

The actual context is that Shuriken misses their Iron Blast attack towards Jin Narumi, busting the wall behind him instead.

Calculation

Pixel Scaled Image (I would like to reiterate this once more, the ellipse is not used to get the actual area effected, just as a reference point for me to work with on my work)

Now the reference tool for my purposes now are these. Now before any of you ask, these are very common within Japanese Buildings, commercial or household wise. Now the length of these machines are 32″ (81.28 cm). Now with that said, let's get the dimensions of the crater.

Axis A: (81.28/144)×417 = 235.3733333 cm

Axis B: (81.28/144)×517 = 291.8177777 cm

Area of Ellipse: pi × 235.3733333 × 291.8177777 = 215783.8196763465 cm²

Now the shape of the crater resembles a lot like an elliptical cylinder, meaning that we need the thickness of the crater to find the volume.

Crater Thickness: (81.28/144)×14 = 7.9022222222 cm

Volume: 7.9022222222 × 215783.8196763465 = 1.705171695×10⁶ cc

Now with the volume found, let's get to finding the yield. Since this is a building, I'm going to be using Concrete Destruction values, specifically the Fragmentation Value of 6 MPa or j/cc in this case.

Shuriken's AP: 1.705171695×10⁶ × 6 = 1.023103e+7 J (9-B, Wall Level)

Results

Shuriken's AP: 10.2310301702 Megajoules (9-B, Wall Level)

Almost near that "+" border, but not yet. Anyways, a number of characters scale to this, so yeah.
