I really missed the point. I didn't realize Hanna was missing untill I find this thread. I'm glad she is recovering and reading new Den-O script.
After she complained about overwork, I hope Ishimori and Toei don't cut off her contract by pushing an end to Hana's role. She's one of my attention in Den-O anyway. I like when she said, "Zettai yurusanai" to the Imagins =D
I do not think it will happen.
