First, examining Ibusuki's secret gender. It doesn't make sense to me that Ibusuki would pretend to be male just so that she wouldn't have to see images of herself over boys. Seems like it would actually be a useful skill to know who likes you are not. On the other hand as a fake male she has to deal with the demon zombies, seems those are much worse then seeing the zombies as yourself.
Imagine meeting a random fat old man on the streets. You don't know him, and he probably doesn't know you. Above his head there's a first-love-zombie of yourself, in string bikini, bound by ropes and gagged, with their crotch constantly hovering in front of the guy's face.
I don't know about you, but I'd be pretty disgusted as a man. I believe a woman would feel similarly disgusted. Or are you saying women are actually shameless and wouldn't even bat an eyelash? How sexist of you.
But then again, you're surprised that she's not using this skill of hers to toy with people's hearts, as any other bitch would. In other words, you either automatically assumed that Ibusuki is a bitch (for some unknown reason), or that all females are bitches.
Chapter 8 already explained Ibusuki's situation pretty well. As soon as she realized what she saw weren't ghosts, she was relieved and accepted the zombies. As she and her surroundings grew older, she started seeing zombies of herself in increasingly revealing clothes. That's when she decided to transfer to another school as a boy this time.
So she is pretending to be male and pretending to hate Taro when she actually wants "to be her true self" AKA female and is in love with Taro. I suppose she could be in denial about the love.
She doesn't pretend to hate him. She's just furious, because he head-butted her instead of giving her a farewell kiss, which is why she has to see all sorts of disgusting sexual fantasies men can have about her, forcing her to dress as a man against her will.
It's not denial, it's resentment.
Grandma wants to reveal her secret so she can have a real daughter, since if she is male, that makes her a different person and more of a disappointment to grandma.
Grandma explained this in chapter 27.
When Ibusuki came back to Japan, grandma was shocked to see how dark and cold Ibusuki's eyes had become, which is why she wanted her granddaughter to be back to her usual cheerful self. She probably assumed that Ibusuki's new persona is linked to her emotional distress, which is why she wants to reveal her secret, so she can be freed of whatever burdens her.
Grandpa wants to hand down leadership of the family business to her, but only if she is a pretend male. Like its inconceivable to give the family business over to a known female. Like being a heir is a macho thing, a sign of being male, as if she accepted said inheritance, it would be like accepting to pretend to be male for the rest of her life.
Because authors cannot possibly add stereotypical old men with traditional and conservative world views without being traditional and/or conservative themselves?
Besides, the story takes place in Japan, what did you expect?
What's next? "The author is against individuality, because most characters are in uniform"?
Like she couldn't be herself, have the same relationship with grandma, and be a heir to the family business, no matter what gender role she was playing. Say if she were to reject gender roles altogether, where would she be left in all this nonsense?
The entire succession plot made up 3 chapters out of nearly 60. It's NOT what this story is about.
This manga is about romance, not gender identity crisis.
All this to me is the author saying Ibusuki's identity is her gender. That would be why she she is mad with Taro, that she felt she had to mess up her identity in order to avoid seeing versions of herself over boys heads.
Your logic makes even less sense here.
It's not because she's angry with Tarou that she decided to pretend being a boy. It's the other way around.
​It's because she has to pretend being a boy, that she's angry with Tarou.
I dislike all this nonsense. It could have been done much better. Very shallow story telling and character fleshing.
I also dislike all this nonsense. You could have done so much better. Very shallow reading and character understanding.
Try again.
