"So... he can talk to the boar, or... what's going on here?" That's nothing too unusual in Japanese media. It even happened in Detective Conan, but with a bear. People understanding animals is in general nothing unusual, the Horse Whisperer, Flippers, Lassy, Free Willy, with a lenient suspension of disbelief Pokémon. Ignoring if they are good or bad. While I thought the Lancer job story was solid, I prefered the Dragoon story (only up to 50 so far) a bit more.
