@TrueGoddessReincarnation is she, though? She's an oddball (like everyone else in the series), but calling her obsessive doesn't seem right. After realizing Ogata likes Nariyuki she even started shipping the two instead of trying to get in their way.
Fun thing: apparently Miyubi solved the P-NP-problem, one of the big currently unsolved mathematical problems, which would entitle her to a million dollar in prize money. But I guess she would be too lazy to collect it.
I'm pretty sure that 10 ton sugar cube was just a comparison for the density and not the actual size of the shells. The professor said that even small meteorites cannot damage a ship, and 10 tons are nothing compared to a meteor, no matter how strong you compress them. However, a meteor-sized...
@Rafaelrgm fair point actually, I forgot he gave her japanese food before. Though for someone from a medieval period, japanese food (or modern food in general) would probably be a shock in the beginning. The amount of seasoning alone would be very off-putting for someone who isn't used to it.
I don't mind if author-san is painting his country in the best colors, but the food being so great? Sorry Japan, but for the rest of the world it's an acquired taste 😄
