There is a scene like that couch scene in Reborn as a Space Mercenary: I Woke Up Piloting the Strongest Starship! Hiro got forced to sit on a small couch with his girls in a tournament to fire up his competitors with jealousy.
Lord did a good job bringing up that the alternative is marrying off to someone she doesn't get along with. This way they can 'build love brick by brick' like Nedd and Catlyn in ASOIAF.
MTL can be great when basically an editor looks over it. It's judged poorly, when it's used by lazy people and/or people with a poor grasp of English.
Glad to see my favorite 'stab them with the pointy end' series continue here.
The stuff with his sisters this chapter is made all the funnier by the fact I'm reading the manga where he romances his sister "The World of That Otome Game is Tough for Us".
Any time I see kukukuku, I can't help thinking of Keyaru.
Actually, the way superior monsters are formed is by many daemons fighting amongst each-other and combining. So it's not like new ones can't be formed.
It's a bit inconsistent to have people wearing business suits in this fantasy setting. But, knowing how web and light novels go, it probably didn't say what they were wearing at all. I mean, that is why they tend to feature cliche settings, so it's easy to fill in the details yourself.
