Tokunaga is a young comedian struggling to make a name for himself when he is taken under the wing of Kamiya, who is either a crazy genius or perhaps just crazy. Kamiya’s indestructible confidence inspires Tokunaga, but it also makes him doubt the limits of his own talent, and dedication to Manzai comedy. Spark is a story about art and friendship, about countless bizarre drunken conversations and how far it’s acceptable to go for a laugh.
