But fleshed out as he may be, he still is a mascot, and I just don't like them (this one can summon demons, he should have used that ability to protect himself from having that laughable dress forced upon him).
Okay fine, here comes the derailing lore explanation.
One can only summon their Persona in such a manner in times of dire stress, and evokers force this state of mind (hence usually being in the form of guns used to somewhat replicate suicide), as such Koromaru needed a similar evoker to summon his persona more freely. Aigis just has one built-in.
Besides, these characters are only really 'mascot' characters because they are non-standard character designs as far as the casts go, as everyone else are just normal people, thus they tend to stand out.
After all, much promotional material does use these characters except in group shots, and it tends to be other members who get first billing on things.
