"Miss Cannon Fodder Wants To Escape Death Flags"
From little of what I've read, the MC was misunderstood as tsundere. It was hilarious, sadly, you need to mtl to read the rest.
...so I want a recommendation with either a tsundere protagonist (misunderstood as one or not) or a misunderstood protagonist's character (I mean, not their power that got misunderstood)
Thank you in advance!
P.s. is there even a novel with Tsundere protagonist?!
Someone mentioned Asuka of Evangelion, and I totally agree. The reason for her tsundere was her inner vulnerabilities and impulsive attitude toward her crewmates which eventually led to her downfall. We see even more of that through her inner thoughts and motives for becoming a pilot in the first place.
Another good example is one of my favorite, if not the most favorite, anime
Toradora for which the example is Taiga Aisaka. The reason for her tsundere is a terrible relationship with her deceiving father and her mother's passing, which doesn't allow her to open up to new relationships. However, due to the growing group of friends and the sense of warmth between them, she eventually opens up.
Another post also explained that it's tough to get this type of writing quality or character development in a novel since many writers develop their characters based on the ones they already know (and most of these are hardcore-badass omnipotent system wielders or delicate porcelain-skinned young beautiful girls) which doesn't allow for
any development since they're already at their peak, physically and emotionally wise. Which is another tip for writers that you should expand your knowledge of personality types through people, or assign a personality type for your character for your greater understanding, to be able to get that type of excellent storytelling.
If you're looking for tsundere in literature or novels, I'd say your best bet is to look for recommendations of characters with strong resolve and/or good character development throughout the series.
