Otaco explores in depth the meaning of cultural identity, its possibilities and trappings, and the ways in which a person can accept, reject, or surpass the elements each culture offers its participants. Paired with a critique of Vtuber idolization that runs rampant in online circles, the film also aims to demonstrate how this virtual escapism, which may seem liberating and bonding at first, actually isolates the persons in real life by making it harder for these individuals involved in each internet niche to relate to those outside of it.
