The interview can be found here. We learn some interesting tidbits:

• 「Deadly Drive」has the theme of life and death
• Kiiyan used to practice the pro wrestling move Cobra Twist on one of his brothers
• e-zuka suggested the use of autotune for  the coupling song「マジカル・ストーリー」
• 「マジカル・ストーリー」has such a different sound from every other Granrodeo song that e-zuka joked people who buy the single for 「Deadly Drive」 will be annoyed when they hear it
• And they both said might never perform the song live (but then, they said the same thing about 追憶の輪郭).
