Kurogane Tama

Oh geez... You two are totally hopeless aren'tcha?

I’m Super Cute and Crazy Strong, belonging to Minato-Shirokane's Denonbu! The Ace Up Your Sleeve for a Thousand Battles! That's me, Kurogane Tama

In truth, I am here to make up for you two's lack of ability!

In my hands, the 'Strongest Shibuya' is merely a pinch!

Tama

Go brew me some black tea

Of course ma'am! Right away!

Add "Aki's personal servant" to that list too The word for servant here has a more negative connotation meaning something like "a person who is only summoned and used for (menial) tasks"

Manga: Koruri

Don't call me a servant! Call me a Maid!

A Hyper Maid that's paid properly for her work!
