This was Toshi's third of the grade after Orochi at Kanoto and Practice of the wild at Magic wood.
Asagimadara is a highball which was first done by Tokio Muroi, who didn't use any crashpads. He needed more than 100 days and suggested 8C+. Toru Nakajima repeated the problem in March 2013 and felt it was probably closer to 8C. The crux is the first five moves.
Both Toru and Toshi says it's a fantastic problem.
