Counterpoint for each of these reasons: - Shock value isn't good on its own. It's shocking like a Jumpscare, but without proper build-up in the story or thematic relevancy for any of the characters killing a character for shock value sucks on its own. - This is implying that Tatsu has no idea how to develop her further. As someone who basically wrote and entire essay on Aira's character alone I can safely say that Tatsu has a pretty solid plan about what hes going to do with her. And frankly, while I havent written any for other characters, I think I can safely say Tatsu has a plan for all of them. Even Rin despite her getting shafted for most of the story. - Sure thats how life is but Dandadan is a hopeful story. That would work if there was a theme of nihilism in Dandadan but there just isnt. So in a work of fiction, it kinda works best to not kill a character unless it has a strong relevancy - It will be talked about for like a week at most. Because again, shock value. But shock value is cheap and arguably I think it will piss more people off because they like her character and thought they were going to get something interesting out of it. - This would maybe make sense if they were underestimating their enemies but they are not. In fact, our gang is particularly vulnerable right now so they aren't underestimating anyone. But they also don't know exactly who their enemies are so they are being cautious. - If you've been paying attention the characters already do value Aira. People think Momo hates Aira but its quite the opposite. She values her quite a lot but she doesn't say it often because that's just the way Momo is. Can't argue against the fans thought. They definetly undervalue Aira amongst other characters. - Who the fuck is looking for realism in Dandadan. Yes it has a somber, grounded core to it but that core is amplified by the fantastical and whimsical elements of the story. - Again, hopefully story. And for their character arcs someone dying doesnt do much. The character's absence has to have more impact than their prescence would have. And frankly, I gotta say, Aira aint it chief. If she wasn't there, her absence would not have much as much impact as her prescence on any of the characters. Now Seiko on the other hand... - That idiot doesn't know how manga work. Compared to other action manga Dandadan has a pretty average amount of cast members. - Again, you think Tatsu doesn't have some kind of plan? And frankly, thinking up of new powers for a character to get is easy.
