"Our unnamed protagonist".
If the author doesn't give a shit about their protagonist, then why should I? They are just as much the person they were on Earth as they are the person they are in the new world. They are also just as important before whatever body swap, gender swap, or reincarnation they endure. I'm so tired of these manga that just flat out refuse to even name or give a face to a protagonist before the switch. It leads to an automatic drop from me anymore.
