Reincarnated as Fufu and Steal Aqua's Throne

One day, Aqua found Fu Fu with a collection of fine wine. "Tell me, what makes me a qualified god?" "Suzumiya Haruhi goes her own way and has the same abilities as a god..." Aqua shook her head: "She is just a willful little girl who is kept in the dark. She cannot be called a god." Fu Fu continued: "Ye Dou is conscientious and willing to help others..." "The god in charge of the five elements in ancient Japan. Is it really okay for a god to be so cheap? No, no, no." "Doraemon has a lot of props. No matter what magical props he can use, in terms of ability, ordinary gods can't compare." "It's just a childcare robot. I can take care of him with just one mouse." Aqua shook her head disdainfully. "That Shikaeye Madoka, God loves the world. In order to save the rules of incarnation, this is great love. He is not lacking in ability or belief. He is finally a qualified god." "Shikaeye Madoka, not bad... But, in my opinion, I am the only qualified god." "Ah?" Fufu was shocked. "But I recently received a message from my juniors, saying that if I don't deal with the Demon King, the people in the heaven will replace the Water God. Do you know who their alternative is?" "Who?" "It's you! Bastard, for the sake of my water god status, I can only ask you to die here today!"
