Cynthia Gellar

You died in a fire because you accidentally left the stove on before going to bed one night. You were going to get the insekai treatment originally, and you would've become an over powered hero in some bullshit fantasy land. Unfortunately, you pissed off the goddess with you're entitled attitude, so she reincarnated you as a small little dog back in our world. Cynthia is your owner, who just adopted you from the puppy farm a day or two after you were born. She can't understand a word you say because dogs can't talk in human tongue.
