[Practical training + multiple female leads + romance + invincible]

The protagonist is transported to the world of Classroom of the Real, inheriting Ayanokoji Kiyotaka's martial prowess, Azusagawa Sakuta's witty banter, Oreki Houtarou's good looks, Ito Makoto's womanizing skills, and Hikigaya Hachiman's name.

In this life, he vowed to carry on the mantle of Brother Cheng!

Transmigrating to a crossover anime world, Rosser finds himself a demon hunter, his landlord is Kayako, and his neighbor is Yotsuya Miko... Is Conan a mystery with an instant-death rule? Help! Where's the Counter Force? Where are the Heroic Spirits? Oh, they're just standing by and watching me die. What, I have a cheat code? But then again, you can only rely on yourself. I'm going to create... a new type of Moon! First, I'll transform into the Abyss Eye White Dragon, create a WarGreymon to give the world a little dragon-related shock, and you'll see, isn't that a dragon? Then I'll create a Five Holy Grail War world, making all the exaggerated descriptions come true, connecting it to the FGO world next door, shifting the blame, and whoever loses becomes a Lostbelt. Type-Moon people: Stop!! And then... Saber: You're Arthur too? What do you mean by "the strongest because the strongest is the strongest"? Goetia: Your Beast Law... wait, what the heck is the Law of Cycles? Gudako: Mashu, could it be that our world is the Lostbelt? Kazuma and Ayanokouji: Commander Rosser is my sun, ah, praise the sun. Poor Xiangzi: Mr. Rosser, a maid's duties don't include anything else~ Tokisaki Kurumi: You scumbag god, watch me exhaust you with my three thousand clones! Also known as "The Birth Diary of the Servant Universe" and "Slaanesh's Daily Life of Having Fun".

A friendly reminder: The protagonist is Ayanokouji from the original novel, whose personality interacts and blends with that of the transmigrator, preventing him from being heartless towards the female characters in the novel. (Since many people might be put off by thinking it's anime Ayanokouji, I want to warn you that the style leans towards dry humor, similar to anime/real life, so please don't be offended if you don't like it.) Ling Xiaolu accidentally transmigrates into Ayanokouji in the real-life school, filling the emotional void in Ayanokouji's life, and then it's all about showing off, flirting, and having fun! The narrative pace is similar to anime, one episode at a time, so I hope you can stick with it; you won't be disappointed!

You reap what you sow; you repay what you help. Wandering through the economically declining Tokyo, surrounded by countless compassionate souls awaiting a helping hand, Akiyama decides to follow his heart and become a helpful 'good person'.
