Creative Thinking Is Everything I Have

Meet Orihara Satoru, a 33 y.o. Game Designer who was about to confess his feelings to an overly cute co-worker. Yes, he ‘was’, because his life unexpectedly came to an end.
He woke up in a new world.
In the world, where 99.9% of the population are reincarnated people like he is, and technology co-exists with magic.
In the world, where every few days Beasts are summoned by a Wave to bring chaos and disaster.
"How will I fare in a world, where everyone is an Isekai protagonist? Also, my build is a random mess and why am I a girl now? Oh, well. Creative Thinking is Everything I Have."
