"The Mona" does not stand, and be fired hame tide 4 suddenly by a Geki piston of the Dotou! Even if I spout the tide how many times, the reason of "the Mona" is just before collapse to the explosion piston which there is not of the Koto which is over even if I reach several times of top! Echo in a room, and screaming of "the Mona" shows the destructive power of the Geki piston!
