Adding functional attachments onto the base model...

...and making sure the user can control them.

Ohh~ As expected of Iroha!!

But... just doing ears is the easy part.

Iroha?

Virtual avatars come in all shapes and sizes! Besides ears, there are tails, and some even have eyes that change color!!

Plus all sorts of weird parts... I'd have to rewrite the entire nervous system!!

This is way too much work!!

Not enough salary for this!!

You startled me...

In that case, couldn't you just make attachments like the ears into accessories?

But then it would just be regular cosplay.

I see.
