When you think about it, she probably has the most natural reaction to having a guy suddenly show up and become manager of a girl’s team (i.e. wtf is this guy’s problem?) but her prickly reaction stands out all the more because the rest of the team have resolutely determined that this it is not a problem.
Anyway, spoiling a bit here, but Ueda does relax a bit and get along better with the rest of the team as the series goes on (all 30 chapters of it). Unlike what you might expect, Masakiyo doesn’t pull a “mighty whitey” and solve all the girls’ problems for them. For the most part they work through their issues together as a team, and Masakiyo is mostly there on the sidelines supporting them. Also there isn’t really any romance in the series, so don’t get your hopes up.
Apparently, after series ended after 30 chapters in Bessatsu Shonen Magazine, it was picked up by Weekly Shonen Magazine and rebooted as the rather more fanservicey 2-volume “Macmillan no Joshi Yakyuubu” series I thought the original ended very well, so I have no real interest in following the ‘sequel,’ but it’s out there
