The car is a Nissan and the "NISEMO" is a reference to its NISMO performance brand. But there is a bit of weirdness that being cartoonish doesn't explain. This looks like an R34 Skyline GT-R with the shape of its headlights, but that model had one-piece headlights. The front bumper also more inline with the R33 with the two square openings below the grille (and it, too, had one-piece headlights and R32s were the last generation with factory two-piece units). There are conversion kits to add the R34 headlights and fenders while retaining that unique R33 GT-R front bumper design, but those also reuse R34 one-piece headlights. The rear quarter window shape is also more aligned with the R33 than the R34 as the later GT-R had a flatter top while the R33 has a rounder blend into the B-pillar.
