"I, Hikigaya, am a legendary agent, a leader in the association, a master of the mysteries, one of the Five Emperors of the Ocean, and the nemesis of the weird." "I have five cousins, a sister, a childhood sweetheart, two ex-girlfriends, a lovely junior, and a beautiful colleague, but no one likes me. I'm a complete loser." The everyday and the mysteries gradually intertwine, and despite our hesitation, we continue to move forward. Cthulhu has landed in New York, and the legendary agent Altria has disappeared... This era needs heroes. "...Stay sane, and follow me into madness." Hikigaya lit a cigarette expressionlessly, put on his sunglasses, and flashed his ID [White Robe Anzai]

The general plot (spoilers included): The male protagonist, Shen Qiyu, is a master fish farmer, master of hatchets, and a master of multitasking. A time traveler and a reborn person (wearing a body), he's died 9,999 times? Each time as a hatchet, which further solidifies his determination to start a harem (reasons: 1. Ending the cycle of reincarnation, 2. Saving girls with personality flaws, etc.). The male protagonist's cheat codes: 1. Rapid "unity of nature" (extreme focus on tasks). 2. Nearly omnipotent skills, allowing him to know future events (he learned this after living for 10 to 20 years before being hacked). 3. Buggy-level physique (a must-have for a time traveler with a harem). 4. The sole male heir to the Shen Qi family, the head of Japan's seven major financial groups (with a step-sister who's obsessed with her brother). The story begins with the male protagonist transferring to a new school and entering his third year of high school. He foreshadowed several female protagonists as a child; he transferred schools multiple times in middle school, planting "seeds" in their hearts. Furthermore, through these transfers, he instilled "guilt" in two teachers during his first and second years of high school. Afterwards, he uses his superb experience of being hacked and his skilled scumbag skills (breaking the heart's defense, closing the distance, high-end pulling), to control the heroine's love, and force the heroine's emotions, increasing her guilt and her ability to accept the harem, expanding the number of women, and working hard to expand the harem to avoid being hacked...

To repay the Chihaya family for their kindness in raising him, Chihaya Tetsuya has been striving to become a top fashion designer. However, even more fearful than the treacherous and ruthless fashion world ahead is the supportive women behind him—Toyokawa Shoko: "Tetsuya-kun, please entrust your life to me." Hoshino Ai: "I'm willing to be your personal dressing doll forever." Nagasaki Motoyo: "Having already lost once, I'll never let go again." ……………………"Tell me...what should I do, Aine?" "It's okay, brother, you don't need to worry about this." Faced with the bewildered Chihaya Tetsuya, a faint smile crossed her face. "Because I'll take care of you forever." "...Huh?" In this world of surging gravity and peril, Chihaya Tetsuya struggles today. ……………………Mygo+ I hope everyone enjoys reading this children's worldview.
