Recently, ” noiseless mountain ” Masahiro Ito is pushing the division of artistic design of an eccentric person of series to go up especially the secret that divulged trigonometry head helmet falls. Masahiro Ito is written, I often am asked, what be after all below the helmet of trigonometry head? The trigonometry helmet of trigonometry head is not its head itself, and I also won’t tell you true body. If knew magic trick,resemble you, so magic do not have what meaning to you same. Interesting is this and ” noiseless mountain 2 ” newsreel of the video that make is contradictory. In newsreel Masahiro Ito ever had said, the set of first game is the person that has mask, became an eccentric person that locks face later, cause a lot of people — include myself — the one part that thinks helmet is trigonometry head body. Triangular itself contains right angle and metamorphosis, alluding anguish, also be in on behalf of an eccentric person the part in game. Masahiro Ito still shared plan of a piece of cut, weigh what be cancelled to this was 2013 ” noiseless mountain ” add makes notional plan. That is to say this series ever had returned Team Silent to develop personnel hand originally in, but still was cancelled finally.
