I find bobom more natural as well and this is why I chose it when I translating the 1st chapter, but the majority seem to prefer ba-dump/badump coz it's more common, hence the change. But thanks for your opinion! I'll think about it for the upcoming series ^^
This is funny as heck. Where has this mangaka been hiding all this time??!!
Also, am I the only one who prefers the "bobom" sfx because it sounds more natural? Idk haha
