Şöyle bir teori yazılmış orojakson'da.
Oden, momo, Kinemon, Kanjurou, and Raizou are already been dead. But their spirit came back to life by Oden's Devil Fruit power. The fruits might works like Brook's fruit. But instead of reviving himself, the user could revive the other at the cost of his own life. The Power is like a Rinne Tensei.
Momo, Kinemon, Kanjurou, and Raizou are already dead meanwhile Oden still at the death door and he decided to use his last dying breath to revive them. One of the reasons is that Momo has the VOAT and Oden knew that it would be very important for"dawn" thing. The other reason and the main one is because a father just can't/won't let his child to die.
Kısaca; Momo, Kanjuro ve Kinemon zamanında öldüler. Oden, şeytan meyvesi gücünü kullanarak, kendi canı karşılığında onları diriltti diyor. Birden fazla kişiyi diriltebilmesine pek ihtimal vermiyorum. O yüzden tutmaz gibi.
