My Ribdiculous Reincarnation

I was reincarnated as "a locker used by the protagonist to hide in horror games." Himina, a female college student, arrives at an abandoned hospital overrun with zombies. I decide to support her from the shadows and begin to secretly follow her— But then,
due to the gods' scheme, I'm reincarnated as a truck that forcibly transports people to another world, and I start sending monsters flying one after another. Furthermore, I'm reincarnated as "the first magic used by a hero who was transported to another world to investigate magical energy." I begin training under the hero Rikyo, but I gradually lose my memories of my past life—

I was reincarnated as "a boomerang that never returned." I became a boomerang made by Kashiwa Taro, who is made of kashiwa mochi, and I try to defeat demons, but it doesn't go well. Together with Tanaka, another person who was reincarnated in another world, I try to escape from Oni-da Island, but──.
I was reincarnated as "an explosion and smoke generated by a signature pose." I was summoned as an explosion and smoke by the signature pose of the Fantasy Rangers, an otherworldly sentai team. The Rangers challenge the Demon King to a decisive battle, but they are no match for my power. The Demon King tries to use his special move to eliminate the Rangers, but I notice his pose──.

I was reincarnated as "the third heroine the yuri harem hero conquered, whose classic attributes were taken by the main and supporting heroines, whose impact was dominated by the later heroines, who was only mentioned by name in the middle of the story, and whose name wasn't even mentioned in the final stages." As an alien heroine who appeared from space, I joined the hero Nante as his companion and set out on a journey. More and more heroines gathered, and the final battle for the main heroine's seat was about to begin, but the goddess yawned and seemed uninterested. I came up with a certain ingenious plan to please the goddess, but...

The gods, exasperated by my unrestrained actions, stormed into the goddess's chambers and pressured her to grant me an exception: send me to a meticulously crafted fantasy world where everything was perfectly arranged, and reincarnate me as the hero who would save the world. Captured by the gods, I was reincarnated, leaving only the goddess in the room. The goddess found a videotape hidden in the souvenir room. The screen, when played, showed a record of all the misdeeds I had committed in my previous reincarnations, as well as my own narration of my life before death. There, the goddess learns a shocking truth──.
