About the last part, how kanji makes a better vocal incantation and mental image.

So what I got from this is the thoughts of a writing system matter because if you imagine the logographic symbols, kanji, that makes magic happen better because it just does. Thinking in Kanji = super magic. Thinking in hiragana = crappy magic. Thinking in sign language = god level magic.

@PhantomStarlight flaws? o:

@Liquidxlax I think it will just melt down instantly, like acid.
But still, I would've liked the artist to make him say it in his mind also, not spell it out loud. Since its isekai and all.

imagine if he said "burn" lol

Reminds me of Konjiki no Word Master except the opposite.

@Andiza, I've reread that comment several times and I'm still not entirely sure what you're trying to say. If you mean he's just using kanji because they're like magic runes, I don't think that's the case since this world doesn't seem to have them and he never mentioned anything that would suggest that in the manga.

@Ruruskadoo kanji (or any symbol writing) and magic runes have more similarities than normal alphabet, you angry about what they do just because "it's different in (insert a place) is kinda stupid thoo

@Andiza yeah, that's the point. Like @VincentYamato said, they're jerking themselves off to how great they are. I gotta say, I find strong nationalism really offputting, it's just going around bragging about how great and wonderful you are while pretending you don't have faults and getting mad when they're pointed out. I don't like it here in America, and it really reduces my enjoyment when I feel it coming through in manga.

To be fair, the inherent meaning kanji characters hold DO convey more than just the sound of the word alone.
Although I'd love to see a japanese author have the guts to emphasize kanji's flaws instead of just their strengths in one of these series.

Magic is often associated with runes and symbols that represent ideas and concepts, so I guess making a connection between Kanji and magic would make sense.
But if they're trying to flex their Japanese pride with the characters they borrowed from Chinese, then that's pretty awkward.

i like how people still forget that this mango is made by japanese people to japanese people and comment "muh superior japanese kanji"

I knew it!! It's just cliche now that the MC can burn the heaven when he first tries Magic... The God rumors may circulate now!!

BURN!

Huh, I expected the workshop to blow up, like Megumi or Zero's "EXPLOSION!"

Perhaps the author will burn the place down to compensate for the lack of immediate impact

Omae wa mou moteiru ...

LMFAO

Well at least Phil is a prince so even if he burned the whole building he can just have it fixed and even renovated, so in that case it was good that it happened?
