So whose the Mantis here? The older brother or the younger brother?

the mantis is the older bro and the insect parasite is the butler

So what about the little bro? The insect parasite you mean the Horseworm.

exactly the lil bro will probably be the inocent guy here or thats what the author wants you to believe(?)

Okay Thanks for explaining. I feel sorry now to the little brother.
