Aww I would've loved a story about her little sister.Loved the story
Miwako is al main character in Paradise Kiss. The heroine for it is a new character but a lot of characters from Gokinjo appear. You should check it out. You can see how Sensei's art and story telling really developed. The fashion in it is awesome too.
Please continue to update
I would certainly love it if someone would pick this up. I had given up on Tomehane! when the Moomin group picked it up after it hadn't been updated since 2012. Now if someone would grab Natsu no Arashi, my life would be complete.
Please update soon
