Starting from Scratch as a Yin-Yang Master

This is a world where monsters, gods, and humans coexist.

Everyone has a chance to awaken as an Onmyoji. Using the power of summoning, they can call monsters or gods to become their partners and fight alongside them.

Natsukawa Rei is an "ordinary" "unlucky" Onmyoji who has a host of Demon Kings from every realm at his side. Together, they "brave every obstacle" on the road to becoming a great Onmyoji.

For his first summon, Natsukawa Rei silently thinks: I want a pretty lady, like Aoandon.

The Demon King who answers twirls his fan. "Am I not pretty?"

For his first awakening dungeon, Natsukawa Rei silently thinks: I want a low-level awakening talisman.

A certain Demon King tosses a glittering high-level awakening talisman and says nothing, just smiling.

For his first competition, Natsukawa Rei closes his eyes and silently thinks: I heard newbies grow stronger by getting beaten up. I'm scared of pain, so please lose quickly.

The Demon King, who has just waved his hand and wiped out all of his opponents, pulls Natsukawa Rei into his arms. "Don't be afraid. I'll protect you."

In everyone's eyes, Natsukawa Rei is an incredibly lucky Onmyoji. He's summoned Demon Kings from every realm, yet every day he goes on and on in a faux-humble way about the pain of not being able to get the monster of his dreams.

One-on-one romance. Couple undecided.

While I'm at it, shamelessly asking you to add my upcoming novel to your reading list~

"The Years I Spent Winning Over My Ideal Man [Anime Crossover]"

Mile's mission is to help people who died with regrets get a second chance at life.

So, with a complete collection of shikigami, he transmigrates into the bodies of:

- The brat who regretted preventing his older brother from forming an alliance with his best friend (Uchiha Izuna)

- The Black Organization member who regretted messaging only her boyfriend before dying, without thinking of her younger sister (gender-swapped Miyano Akemi)

- The vice-captain who regretted letting a misunderstanding lead to her comrade's death as he avenged her (gender-swapped Matsumoto Rangiku)

- The godson who regretted letting anger cloud his judgment and get his dad killed (Portgas D. Ace)

After Mile completes his missions:

The brat becomes a key figure in bringing the two clans together, even sacrificing himself to take out his white-haired archenemy on his clanmates' behalf.

From the start, he takes control of the boss of the liquor company, and an ordinary member on the organization's periphery rises to become the mastermind behind the Black Organization.

He closes the gap caused by failing to reveal the truth in time, preventing his best friend from dying to avenge him before it happens.

The hot-tempered godson suddenly becomes a nanny, sparring every day with his dad, who doesn't take care of himself.

Actually, this might be a wish-fulfillment romance? Other worlds to be developed as inspiration strikes.
