[Kakegurui] + [DB Apocalypse] + [Crossover of Similar Anime]
Hey, as the eldest young master of the Teiai Group, isn't it perfectly normal to be a spoiled wastrel?
As a spoiled young master, you need to have three defining traits.
First, know how to squander money: use the group's funds to indulge yourself, build a harem, turn a small stake into a fortune, and even launch a hostile takeover of your own company.
Second, have a big harem: a whole crowd of maids and servants, all won fair and square, each with a special skill.
Third, have something wrong with your head! Answer: When you spend every day hanging out with all kinds of crazy girls, how could you not go a little nuts?
Fourth... What, you want to know what I'll do if my fiancee, Kirari Momobami, gets angry?
Then I'll toss her into the water!
