On Kabuto site I was able to translate this from ep 25 summary using google mind you,but it looks right.
Opening the unknown door of the Shibuya ruins, the heaven road which enters to in (Mizusima [hiro]), Kagami (Sato 祐 the basis), from the [hi] (Satonaka 唯).
There was the room like the operation room while many years are left.
Kagami who loses voice in the egg of the worm of the alcoholic soaking.
But, those where they can be surprised “masked rider plan” were no volume thing file which is written.
“The No.1 1971 April 3rd ~” among those Kagami who takes one volume which is written in the hand will be amazed.
Because “God of fight, to do to be chosen in [gatatsuku], the person and Kagami new” it was in.
As many as 35 years why [gatatsuku], why before Kagami's name…?
Here the normal kana also..
渋谷廃墟の未知の扉を開けて中へと入った天道(水嶋ヒロ)、加賀美(佐藤祐基)、ひより(里中唯)。
そこは何年も放置されたままの手術室のような部屋だった。
アルコール漬けのワームの卵に声を失う加賀美。
しかし、彼らを驚かせたのは「マスクドライダー計画」と書かれた何冊ものファイルだった。
その中の「No.1 1971年4月3日~」と書かれた一冊を手に取った加賀美は愕然とする。
中には「戦いの神、ガタックに選ばれし人、加賀美新」とあったからだ。
35年も前になぜガタックが、なぜ加賀美の名前が…?
They clearly knew Kagami was going to be Gatack way before hand,but how? I think the future Kagami wrote it down in journals.
