I don't speak or read Japanese either but I do have experience translating from other languages. Best guess is that Sewing Arrow, etc is a a technically correct literal translation. That's not how you'd say it in English though and it sounds somewhat off. In cases like this you're...
Whenever I see attack names like Sewing Arrow (and the previous translation, Embroidery by an Arrow) I always wonder, is that actually supposed to be Needle Shot, or something? I feel like it's being translated too literally.
That was decent ending, but I definitely agree that it felt like the series got cut short rather than reaching a natural conclusion. Overall I really enjoyed it though.
It's almost for sure a time travel thing. I'm guessing she's going backwards so while from his perspective this is their first meeting, for her it's their last.
Despite the title I did not expect her to literally explode.
That said, this is definitely one of the weaker stories of the bunch. It's not bad, but it's pretty boring.
