The only part that was planned was how the moon was blown up and that he didn't want to blow up the planet and would just explode and made a promise to their former teacher. Everything else was just made up as the artist went along.No way just revealing that Kaede was muh acting all this time and actually had tentacles too was planned.

>>281946290Who nows, maybe the source started foreshadowing it a few chapters in advance, but there's no way it was actually planned from when Kaede was introduced.
>>281944397>>281947356IIRC you could already see Kaede's tentacle being stirred slightly in the chapter when Korosensei fought Itona, so that's quite a bit of time beforehand, long before the "pudding" chapter.
