When the Enemy is about to attack Gugu, Fushi springs into action and shields his brother from the twisting branches by creating a number of spears to parry them. I guess he has learned a few things since his last battle! Gugu wants fight beside him, but is very lucky to survive when the Enemy throws him across the forest.
It may just be the still Booze Man installed in his stomach that saves him, as he proceeds to barf out all of the liquor stored there. When his torch ignites the liquor-vomit, Gugu gets an idea for how he can help Fushi, and races home. On the way, he turns completely red, drunk off the liquor that escaped the still, while Rean is about to be carried off by her helicopter parents.
Drunk Gugu is naturally a less inhibited Gugu, so he doesn’t mince words about loving Rean more than anyone, no matter to whom she’s betrothed. In any case, he’s not there to solve her family drama, but to get a refill of Booze Man’s best booze.
Pioran, the only other person to have witnessed the terrifying power of Fushi’s Enemy, insists that Booze Man do as Gugu says. The old man fills Gugu up with his strongest stuff and sends him on his way, while Pioran stops Rean’s parents from taking her and leaving…because it’s not safe out there.
Gugu, having sobered up, arrives to find the Enemy has absorbed Fushi’s Giant Bear form, and there is no sign of Fushi. But it’s soon apparent that the Enemy, essentially being made of wood, is vulnerable to fire, and Gugu has a fresh bellyful of fuel to play with.
Using his boozy fire breah, Gugu burns the Enemy to the ground, freeing Fushi, who is only flowing light and energy before transforming into a rock, his first form. When Gugu picks him up, he transforms into a wolf dog, and the two tussle mirthfully…though Fushi keeps his promise to bite Gugu if he came back!
The next morning Gugu and Fushi return to the Booze Man’s house where everyone is very confused about what happened (though Pioran probably has a pretty good idea). Gugu celebrates his return by cooking up a feast so delicious, Rean’s parents deem him better than their professional chef.
Fushi, back in the same clothes and with the same rope as the boy when he died since he “reset”, greets his maker, whom no one else can see or hear, outside. The creator tells him in order to become stronger, he cannot be sedentary, but like Rean with her parents, Fushi protests. He wants to stay. The creator tells him that’s also an option.
Back inside, Rean prepares to leave with her folks, and Gugu dispenses some precocious wisdom: The people who keep us alive aren’t necessarily good people, but we aren’t so weak that we can’t endure it. Granted, he’s had to endure a lot more than Rean, but it’s all relative!
Fast forward…four years. Gugu is no longer a pot-bellied boy, but a swole young man, having never stopped his fitness regimen. He continues to assist the Booze Man and feed him and Pioran (who still starts eating before everyone comes to the table). Rean still “runs away” from home on the regular, to see Gugu and Fushi.
And Fushi, having watched Gugu and Rean grow, has himself grown “older”; his hair growing longer and even gaining a slight stubble on his face. He also speaks a lot more naturally, which isn’t surprising considering his teachers and how long he’s been with them. The tenth episode of a planned twenty ends on Fushi’s new family happily enjoying a meal together. If only that happiness could last…
