Question about Maho and Koyuki relationship at the end of Beck Manga. Maho leaves Koyuki behind for studying in England and they agree to be in a long distance relationship right? But the thing what I wanted to know was, did Maho ever mention in any part of the manga, that she was coming back to Japan after finishing her studies? Or is gonna be staying in England for good? I know they are going out and the relationship status isn't cleared up at the end as Maho isn't even shown in the last chapter. But I know they were very much in love with each other and never actually broke-up but if she didn't mention of ever returning, its as good as any suggestion that they aren't together at the end right?

Well, Maho was shown in the last chapter. She didn't talk to Koyuki, or at least that's what it looks like. Now, the real question should be, "Why was Maho at the Grateful Sound?" Earlier in the series, when Koyuki accidentally "gets stood up" in England, and they finally end up seeing each other in Japan, Koyuki says that that is the last time he saw Maho in Japan. If that's the last time, why is she at the Grateful Sound? It's very unlikely that they wouldn't see each other there. See the inconsistency?

Anyway, back to your question. They didn't say anything about it explicitly. However, going back to my earlier point. Koyuki said that time was the last time he saw her in Japan. Keywords: in Japan. That means he's seen her more times outside of Japan. It's not much, but with the band starting to make it big, I'm sure they would have more opportunities to see each other. But really, you can assume anything.
