Hello, this is Rikao Yanagita from the Institute of Science and Technology. I enjoy thinking about manga, anime, special effects programs, etc. from the perspective of science fiction. By the way, this research report is.
I don’t read many “different world” novels, but my friend recommended me to “Bless this wonderful world!” By Kadokawa Sneaker Bunko. When I read, isn’t it funny?
“The dull hero lost his life and was reborn in another world and made a big success” is according to the pattern. However, Kazuma, the main character of “Konosuba”, died of a heart attack when he was about to be run over by a tractor instead of being hit by a truck, which is the standard cause of death in “another world”! It’s a pretty dull guy.
Such Kazuma reincarnates in a different world with the goddess Aqua and embarks on a journey to defeat the Demon King as an adventurer.
However, this aqua was an unusable goddess. Although she is a beautiful woman, she looks from the top, is troublesome, loves alcohol, is vulnerable to being hit, and immediately makes a loan.
When a dull adventurer and a goddess with a personality problem couldn’t help, when we recruited friends, we found two girls who were biased around Aqua. A wizard who can only use explosive magic and a knight who can only defend.
In the end, all the bad people gathered, and I wondered if I could beat the monsters with this, but the owners of this crazy ability played an unexpected role. That’s the fun of “Konosuba”. Sada.
There are many scientifically interesting points, but this time I would like to consider the “explosion magic” released by the wizard Megumi.
I made a crater with a diameter of 90m
Megumi is a 13-year-old cuckoo with a black cloak, black robe, and Tongari hat. Although his eyes are not bad, he hides his left eye with an eyepatch, which means he is suffering from Chunibyo.
However, his profession was “Ark Wizard (advanced wizard)”, and he appealed that he could use “explosion magic”, which is difficult to learn, and became a member of Kazuma’s party.
In fact, the power of Megumi’s explosive magic was tremendous.
After chanting like “My name is Megumin! Being the best magical user of the Red Demon Tribe and manipulating the explosion magic!” When you shout, A flash of light runs, and a huge explosion occurs.
When it was released to the Demon King’s cadre, Verdia’s subordinates, a huge crater was created in the city square, and all the monsters were wiped out.
This scene is easier to understand in anime than in novels, so let’s take a look at that description.
Then, the diameter of the crater generated by the explosion magic is about 90m by eye. Generally, the depth of the crater is about one-fifth of the diameter, so if the depth is 18 m, the rock in the hollowed out part is 160,000 tons.
The energy of crushing this is 12 million kcal. 12 tons of explosives.
That alone is great enough, but this is not the only energy that Megumi has released. 12 tons of explosive is the energy to “crush rocks”, and it is also necessary to “blow off the crushed rocks” to form a crater.
Looking at the depiction of the anime, there were only a few rock debris falling around the crater, and there were no signs of people nearby or the city being damaged by the debris scattering. This means that most of the rock fragments would have been blown off quite far.
Here, let’s assume that the debris was blown an average of 2 km. Then, the energy is 402 million kcal, which is equivalent to 402 tons of explosives. Much greater than the energy of crushing rocks.
And the total of both is 414 million kcal and 414 tons of explosives. That’s 1035 energy equivalent to the 1,000-pound bomb on board the bomber. Amazing!
Megumi can release such explosive magic. With this wizard, Kazuma’s party would be rock solid … but it wasn’t that easy.
Megumi, who says, “I only like explosive magic,” can only use this explosive magic. I have no intention of learning other magic.
Therefore, when defeating a frog monster or a cabbage monster, there is no choice but to use explosive magic equivalent to more than 1,000 bombs of a bomber. It’s too wasteful.
One of the charms of “Konosuba” is that the dull Kazuma gradually becomes better as he travels with such friends. If you are interested, please take a look. it’s fun.
