In Arknights, but I’m a Tactical Doll

A young woman struck it lucky: she transmigrated, and even became the tactical doll character she had created herself.

She also got bound to a useless System that could only do backflips

By all rights, this should have been a journey from one life to another, reaching new heights!

And yet...

Selena: “You’re telling me I’m supposed to transmigrate where?”

The young woman held the black cat System up by the scruff of its neck and asked with a completely serious expression.

(The summary is beyond me, so I just threw something together.)
