Wow, I didn't even know we had a muscles
tag. This story was a big surprise. You can easily tell it's doujinshi and not manga -- because, really, I doubt there's any manga magazine out there targetting the "yuri between huge musclewomen" fan audience segment.
Great plot, good characters, wonderful translation job on the dialogues, I'm really happy with this release... even though there were practically no kyun moments between Koga and Sawada. >_< I suspect Sawada is your typical hetero-by-default MC and, so far, she hasn't even realized Koga may be attracted to her. Her attitude when Koga asks her out is like 'oh, a date between girls, how relaxing, no dressing up, no trying to impress, no sexy stuff, just harmless easygoing fun' which doesn't seem to be what Koga has in mind at all, hehe.
