Oof, Paru spent so long setting up for the Melon fight, that she had to remind us why they were fighting in the first place. I think the fight will go out the same way the quiz went, Melon's textbook knowledge of animal society(and it's flaws, on paper) versus Legosi's well-lived(for a 17 year old) life experiences, and what he gained from them. This also practically solidifies my theory that their fight will end in a draw. Both sides will acknowledge the problems of society, and work together to improve it, with Legosi being a shining hope as a Beastar, and Melon helping those that were ignored by socirty as the Shishigumi boss.
On the note of Legosi-shipping, I think what most 'fujos' have with female characters don't contribute much to the fights. I mean, Louis gets his leg eaten, Pina risked his life to ensure that Legosi could stay alive till New Years, and Yafya is a fuckin badass. Haru is suprisingly not very different from other Shonen girls though. She for the most part doesn't take much of an active role in the manga. She's either arguing with someone, or observing animal society(Which is a very, very important part of the story. I predict more Haru-monolouge segments after the Melon vs Legosi fight). Of course, this is the equivalent of saying that Goku and Piccolo should have fucked after the Namek saga, yeah they had great moments, but that's not the point of their chemistry goddamit.
As for Haru being kinda insufferable and a dick, yeah. Everyone's kind of a dick. Louis is a snooty, emotional deer. Bill is a loudmouthed dickhead. Though, Haru's flaws are definitely more extreme compared to the other women in the series, but that's... quite interesting, no? Having a 'better, not as dickish' girl for Legosi would be 'nicer' for him yeah, but come on, it wouldn't be interesting. While it might be possible that yelling 'STOP BEING A FUCKING IDIOT LEGOSI/HARU' would get boring, I think their relationship to story of opening wounds, new and old, and learning to heal from them, is what makes their relationship so cathartic in my eyes.
