Cinnamoroll designer Miyuki Okumura also happens to be a history buff with a special interest in Oda Nobunaga, and is a fan of the Oda Cinnamon Nobunaga manga.
The collaboration is taking place both on Cinnamoroll’s Twitter and Oda Cinnamon Nobunaga’s Twitter, where the same art was shared with commentary from each character.
Cinnamoroll comments about meeting a new friend who shares his name, while Nobunaga notes meeting a “weird-looking dog” at a trendy café.
