So like, after reading the manga and watching the anime, I just need some time to process.
First things first: Haruki (brother), Kiriko (sister), Kiruko (brother + sister = MC)
It seems that Kiriko and Robin had some sort of history together before everything went to shit. In ch. 33, Kiruko had a flashback from Kiriko's POV where the dialogue says "Haruki always sleep really well/is a deep sleeper" and it's confirmed in the anime that Robin was the one who said this. This flashback is Kiriko's POV, and it looks like Robin and Kiriko were in the same room together while Haruki was sleeping next to them. This flashback was triggered after Kiruko got raped by Robin. And it seems that the body remembers sensations/has memories of the original person. So I'm speculating that Robin may have had sex with Kiriko before she died (whether it's consensual or not, we don't know).
On the other hand, I am speculating that Robin was the one who shot Kiriko in the head. When Kiruko found Robin again after 5 years, Robin expressed a shocked/scared face. Probably because Robin was surprised to see someone who he thought he had killed. Kiruko says that he can recall his sister's memories, and in ch. 33, Robin's face was shown next to a gunshot sound. And in the anime, the gunshot sound was associated with Robin's face as well. So it could be that Kiruko saw Kiriko's memories of being shot by Robin. In ch. 53 when Kiruko met Doctor Sakota again, the Doctor said "When she was brought before me, your sister had a bullet hole in her head." Anyway, we don't know what happened after Kiriko tried to save Haruki from the Man-eater... all we know is that Robin's gang is usually the ones who show up to deal with the Man-eaters. So it could be assumed that Robin and his gang came after the Man-eater who attacked Haruki, and some sort of altercation between Kiriko and Robin happened. Anyway, I'm just playing a guessing game at this point.
I'll continue waiting for updates.








It's so wild to me that I used to read Sentinel/Guide fanfiction and to see the Sentinel!verse in BL... it's cool to see it in manhwa but makes me sad that no one knows that Jim and Blair are the original Sentinel (I guess they're calling it 'Esper' now) and Guide. Can't beat the OGs.
I love all BLs with Guides though, makes me feel nostalgic.
It’s so fascinating to see old fandom fanfic tropes built into Manwhas and Mangas. I love love the Sentinel/Guide au so I am more than happy to gobble it up. Some of my favorite fics are based on it!
A/B/O too which started in the Supernatural fandom. It’s amazing to see how complete the world is now with new authors adding to it until it now has its own rules and conventions. I love love the see new twists on it and how some authors play with the gender roles and what it means. It’s a great reflection of how a concept is used to explore our real world heirachys and the patriarchy we live in. Sorry to hijack your comment but it’s rare to see old fanfic tropes talked about here. I feel an ancient person sometimes coming to this site.
Wow that's interesting to know! Nvr knew that's the OG. The very first time I came across sentinels and guides was from the novel Heroic Death System
This was my reaction too! Also when omegaverse started showing up in webtoons and manga when I knew it from western fanfiction . I was like "Bro, what are you doing here?! HOW did you get here?!?! I have questions!!"
(although I never read the original, my first introduction to guideverse fanfiction was a combo of guideverse and omegaverse and it was JohnLock, LMAO!!)
