In a very unexpected update, CLAMP-NET announced the covers of Tsubasa #18, due to March 16th:
Deluxe illustration looks so preeeetty ! Congratulations for everybody who bet on Subaru ! xD
EDIT: There's a chance CLAMP might have done it on purpose since today is Subaru and Hokuto's birthday.
Additionally, CLAMP
confirmed what I had previously posted about their appearance on Wanna Gonna, scheduled for the next 25th. It says the show will feature the production of a collaboration kimono manga between CLAMP and the show's MCs. Also making an appearance on the show is Katsumi Yumioka, the owner of a second-hand kimono shop in Tokyo, who participated of a special talk with Mokona in her book.
On another note, they inform that tickets for Mokona's sign sessions in Shibuya and Ikebukuro are sold out.
