Maybe it would be interesting a story the Black cat

This black cat is the Shingo same?????

Which manga begins history of Shingo?????

You'll find the list in the comments before the "topics", thanks to KyoZaNa :
"Kuroneko Series (Spin-Off of 3) - Black Cat x Leopard
-- 4.1 Kuroneko Kareshi no Asobikata
-- 4.2 Kuroneko Kareshi no Amaekata
-- 4.3 Kuroneko Kareshi no Nakasekata
-- 4.4 Kuroneko Kareshi no Itoshikata
-- 4.5 Kuroneko Kareshi no Afurekata
-- 4.6 Kuroneko to Kareshi to Ouji"

That's the order?
Thanks

For the story of the black cat, yes !

I think so

Shingo the adorable black cat has a full series for himself, called kuroneko kareshi.
