Cain finds himself reborn into the world of an Otome video game. He’s brought with him the memory of his past existence as a Let’s Play Youtuber. He is now an older brother to a young lady meant to be the rival and strategic enemy of the game’s female protagonist.

However, his mind is still that of a modern-day man in his thirties, and he can’t help but to find his new little sister adorable. Blinded by love for his charming sister, he tries to stop her from devolving into her fated role as a villainess.

In order to stop the world from following the disastrous Assassin Route laid out in the game he remembers, he attempts to take a future assassin under his wing. He also tries to prevent a marriage to stop the world from following the Crown Prince Route.

For the first 20~ chapters I thought I knew exactly how the novel was going down. Low and behold I was surprised with actual conflict and character development. Which is cool but I H A T E how it was done. This happens in chapter 23 which I've marked as a spoiler. Chapter 23:


In this chapter he assaults the Crown Prince (4yr old) for injuring his sister (4yr old). This is done in front of the Queen, in public.

The MC, awaiting punishment, starts breaking down and it is really well written inner-turmoil. He even starts trying to imagine a controller in his had to return to when it was just a videogame and little consequences.

HOWEVER the public opinion afterwards from the women at the event is 'Oh what a gentlemen he stuck up for a girl'. He is 7 using magic on a 4yr old who pushed a girl down. He doesn't get punished at ALL and is then allowed to hang out with the prince all the time.
The little f*cking psychopath.

I really like how the MC is written, he has high emotional intelligence but it's lopsided since he's a toy salesmen. So he has the ability to care for our villainess but not the wisdom or maturity to do what's best for her. His well meaning actions are negatively affecting himself and others. I don't mind very flawed characters but the ages completely ruined my immersion. Had this conflict been at the academy, maybe a decade later (14-17yr old), I think I would of loved it.

It’s good and refreshing. Many of these trope novels start good but devolve into generic tropes and bland or boring characters. For now, the writer has stuck to the overarching theme and in a mere 25 chapters unfolded a series of complex characters. My only critic is that I foresee that protagonist is sometimes unreasonably sis con. I would like for him to develop healthy relationships outside of his sister, but low and behold and the recent chapters are already going in that direction.

conclusion: it’s a good, casual and fun... more>> read with touches of complexity. <<less

After reading Chapter 21, I think I like the direction where this story is headed.

My initial thoughts on the series was that it would be an otome game isekai with typical incest vibes based on the title. But pleasantly enough, it's more wholesome than expected. Even though the MC is a supreme siscon, his end goal is making sure his sister avoids becoming the villainess and that she attains happiness above all else. This particular excerpt from Chapter 21 I think perfectly displayed that.

... more>>

"You don't have to keep reminding me, Mother, " said Cain. "My goal is to become great at embroidering so that I can one day present Diana with a beautiful wedding gown."

Elise had lost count of how many times she had warned Cain about the coming meeting. This time, though, his response was something she wasn't expecting. She widened her eyes and looked at him.

"Cain! So you do want Diana to be married off, after all, " said Elise.

Upon hearing those words, Cain smiled, sadly.

"What kind of monster do you think I am?" said Cain. "I want Diana to be happy, above all else."

"I thought that you might be an obsessive older brother who planned on never letting her leave the household, " said Elise.

"Of course not. My main goal in life is to ensure that Diana will be the happiest girl in the world. I want her to be happier than anyone, at all costs, " said Cain.


I also think that his sister has been written pretty well so far as the story's portrayal of her has been pretty believable of what a child should act like. She's a pretty big brocon as well, but it didn't feel like that characteristic was particularly as overwhelming as one would expect from imoutos in these types of stories.

Another interesting aspect of the story is that because he's trying to prevent his sister's villainess end, he's trying to round up the capture targets of the original game and make sure they don't end up being the cause of her bad end. So far he's already met one of them and befriended him and their dynamic as friends is actually pretty hilarious as he often plays the straight man to the MC's siscon tendencies. So it'll be interesting to see how the MC will interact with the other capture targets as well. <<less

it's what's on the tin, main character reincarnates as one of the capture targets of an otome game, becomes deeply attached to his younger sister, and is working towards giving her a better future, at chapter 9 not much has been done yet, other than interacting with 1 of the other capture targets, but it seems like it will be a decent enough read to pass the time

Ok so ive tried it out and it was interesting but I've noticed somethings like why the hell is the MC playing an otome game and for some reason after the encounter with the child assassin it seems to be leading to the direction I detest (bl or yaoi) so I search it up and found a forum and based on the spoiler they gave there's a chance so nah im out

Im not saying its a bad read but atleast put tags to make things clear

Ow and if ever im... more>> wrong pls contact me since I think this has a potential <<less

The novel itself is fine but I hate the website that the translation is posted on. It's so ad infested its nauseating and sometimes im not even able to access the website due to google telling me "your connection is not private".

We are still in the early childhood part of the story, so it's mostly heartwarming interactions.

So far this is actually a really refreshing novel. The MC isn't pervy, depressing, or a god among men.

Yes he is a siscon but he doesn't hold any romantic feelings towards her (so far).

... more>> Yeah, the sister is a brocon, but it's just a 4 year old that has no other children to interact with daily.

I think Chapter 23 is the strongest so far, it shows us that the MC despite being focused and healed by his sister is still in an otherworld that lacks the conviencies of the modern age.

There has been some minor worldbuilding and we only saw a glimpse if magic, but I am hopping the author expands on it a bit more. <<less
