From Trigger Magazine #007:

Episode 6 was quite the ride. Sanageyama is too much of a man. You see yakuza's cutting their pinky to set matters straight, but blinding yourself is pretty steep. Especially when sight was Sanageyama's most prized ability. I'm sure a lot of viewers out there became Sanageyama's fan with this episode.

『キルラキル』６話いかがでしたか！？猿投山がやばすぎる。これぞモノホンの漢。覚悟の度合いが違いすぎますね、ヤクザのけじめってレベルですよ！今回のお話で猿投山ファンがかなり増えたと思いますので、今週は猿投山の原画を何点か載せさせて頂きます！
