「Demon lord, is such a thing your『trump』?」
「My【Lightning】is『such a thing』, you say!?」
「Oh, I can also do a magic of that level.」
「I-, Idiot.
I’m the only one who can use【Lightning magic】!」
「Well, yes, now that you mention it, it’s not like that though?」
I crouched down near the Demon lord―
and struck a【Lightning】thicker than that of the Demon lord’s.
「Hii!」
The Demon lord screamed. *Pukusukusu*
I became interested and dropped lightning many times.
「Hiii!」
The Demon lord was paralyzed in fear.
「T-, The magic uniquely for me……」
「It’s a story until several months ago that there was only 1 person who can use Lightning magic.
Now, there are 4 people who can use it including you and me.」
「I-, It’s a lie!
The only one who can use this magic is the chosen, it’s a symbol of a king……
And precisely because I mastered this magic, I became a Demon lord……」
「Is that what you think?……
How should I put it, did you think that you already mastered Lightning magic when you can only use it as far as【Lightning strike】?」
「N!?」
「I mean, you can only use【Lightning strike】,
can you use the magic after it?」
「T-, There’s more after it!?」
「Alright, oniisan, I’ll show it to you especially.」
After taking a dignified pose―
I summoned that fellow.
「【Summon Lightning spirit】!!」
「Ta-dah! I’ve arrived.」
「W-, What on earth is this!?」
「You’re that Demon lord-kun I wanted to meet all the while,
you never improved,
I’m getting impatient!」
「What is this!!?」
「This fellow is the Lightning spirit.」
「Spirit!?」
「Demon lord-kun.」
「Y-, yes.」
Why is that this Lightning spirit seems bossy?
And what’s this, the Demon lord sat up respectfully as well.
「If you only practice【Lightning strike】,
you will never be able to use Lightning on other things.」
「N!? But, since it’s Lightning magic,
isn’t it natural to practice【Lightning strike】?」
「You don’t understand.~ Seiji, show this Demon lord-kun your magic.」
「Eh, why must I do such a thing?」
「As one of the only 4【Lightning magic】users, don’t you have such a thing called camaraderie?」
「*Sigh* Finee!」
I showed the【Incandescent light bulb】magic to the Demon lord.
「This is Light magic!?」
「No, this is Lightning magic as well.」
「No, but……」
「Seiji, explain it.」
「So troublesome.
In short, when lightning strikes it flashes, right?
Originally, Lightning possesses power to emit light.
Just now is the magic that produced light.」
「……」
Demon lord has been lost in thought.
「Show that thing, Seiji.
You know, the thing that can become warm.」
「【Heating wire】magic.」
I picked up a wood that had fallen nearby,
and heated it up to the ignition point with【Heating wire】magic and―
the wood began to burn vigorously.
「Fire magic…… or, not?」
「No, this is also【Lightning magic】.
When a tree is struck by lightning, it bursts into flames, right?
In other words, Lightning also has power to burn things.」
「I……
understand nothing about Lightning……」
「It’s such a thing.」
「Demon lord-kun, do you understand that you need to practice magic other than【Lightning strike】properly as well from now on?」
「Spirit-sama, I understand.」
「Umu, with this, I’m going to return.
You, summon me next time!
Well then, farewell.」
