I.R. (Corrector Yui)

I.R(アイアール) can install and summon the other software if they are found first.

When he is with Yui, he can download the Elemental Suit, causing her to transform into her virtual heroine form, Corrector Yui.

I.R can also drag her into the ComNet if she speaks the password "Corrector Yui Enter!"

I.R looks like a flying mechanical racoon, and is by far the only non-humanoid program.
