Licensed by Bushiroad and published by Tokyo-based company Kadokawa Shoten, a Cardfight!! Vanguard novel has been announced. The author is Bandana Aoi (番棚葵), who is like many names for Cardfight, a fresh face in his field. According to his blog, he was born on October 24th. The novel will be in paperback form.
The novel is to follow Sendou Aichi as he meets a new character, Hamane Hiro (浜音ヒロ). Like the Aichi of years past, Hiro is a lonely boy and a newcomer to Vanguard. Sendou reaches out to teach him the fun of Vanguard. Worth noting, Hiro's surname contains the kanji for beach and sound.
"Cardfight!! Vanguard" will be available on Japanese shelves on May 15th, 2012. It will retail for 714 yen, about equal to $9. The book's ISBN is 978-4-04-631239-6-C8293.
Update: The author's name is Bandana Aoi, not Hatana Mamoru as previously stated. Furthermore, Hamao Hiro is actually Hamane Hiro. The confusion stems from the possible readings of their kanji. Bandana Aoi appears to be a pseudonym.
