After a long day of classes, our protagonist goes to sleep only to wake up as a baby in the middle of a literal wilderness. He has his memories, his adult consciousness, and his otaku knowledge, but unable to defend himself. Alone on an altar in a forest that feels far from Earth, he discovers a big, ancient statue that looks like it belongs to a forgotten cult.
With his past-life name a "blank slate" and his new body barely able to crawl, he must use his 22 years of gaming logic to survive. In a world of magic, strange emblems, and potential human sacrifice, the quest for survival starts before he can even walk.
