The world of Monster Hunter Stories is carefully crafted with specific types of monsters and characters. If a character or entity is not recognized as part of the game, it means it doesn't exist within the game's framework for combat and interaction. Killing is restricted to the monsters and npcs that are officially part of the game, so you can't kill unrecognized characters.
In Monster Hunter Stories, the gameplay is centered around the pre - determined monsters and characters. Strange or unrecognized entities that are not part of the official game content cannot be killed. The game mechanics are set up to handle the specific mons ters, bosses, and npcs that are part of the game's lore and design. So, the answer is a definite no.
No. Monster Hunter Stories has a set list of monsters and npcs. You can't just kill any random or unrecognized thing. Only the ones that are designed to be in the game's combat and interaction system are available to be dealt with in that way.
