Purchased, because I've enjoyed Takahahi's perhaps most known series, Captain Tsubasa, and since it's very hard to find anything on this series, I was curious about it. In my opinion, that storytelling is much more refined; we meet the protagonist when he has to deal with living in the shadow of his famous older brother and the constant comparison to him.

I'd also like to take a time to say, that the shop's service is truly great. That's the only place I know of, where I can purchase whole sets of series, including not recent, thus hard to find ones, at very reasonable prices. The tracking is always included, parcels arrive very fast, and the packaging is very careful, so they arrive in perfect condition. There is always also a small gift, included.
