Kagami and the group have gone 10 year back into the past. A couple of back stories and confessions revealed, but...

Following the confession from chapter 9 (actually 2 confessions) MC gets angry at blondie because he doesn't believe Loli could be like that, so they get separated. MC goes to Loli's house and finds her dad (?) at the entrance (the house is quite big, not like a mansion but, you get the idea) here MC talks with loli's parents (?) and the loli from that era appears, cute stuff happens and MC finds that his younger self is also there. Meanwhile, Pervert is on his appartment jacking off to Tits (yeah) and he sudenly sees Blondie being hit on by some thugs.

Back to MC, more cute stuff, young MC leaves the house and while everyone else is busy, MC goes to loli's room and finds several drawings who look exactly like the Mahou Shoujo from the future, including small toys. Loli's father is watching him from the doorstep.

Loli's dad asks him what is he doing there and is holding a kitched knife, MC somehow brushes him off but takes a small toy resembling a Mahou Shoujo (the giant one that had her head upside-down) from young Loli's desk (it feels weird to call someone "young loli" but whatever). MC leaves the house while Loli's dad still watched him from the window.

Back to blondie, it seems that the thugs took her to a karaoke place with food and shit, the thugs want to rape blondie, she resists kicking one of them in the face, one of the thugs pulls out a knife and threatens Blondie, but before they can do anything, Mute guy appears with a baseball bat and takes them down, Pervert is also there and I think he explains that he found him somewhere. Back to MC, he's alone in a park watching at the Mahou Shoujo toy, a girl with glasses aproaches him, he tries to brush her off but she insists that he should go to her house. The girl is a mangaka btw, after some dialogue in which MC is still mindfucked, he takes a shower and relaxes a bit, he goes to sleep and mangaka girl sleeps with him (not having sex, just right next to him like a mother).

Back to Pervert, he beats the thugs who are now tied with a rope, he also ties Mute guy and Blondie because he wants to find the younger Tits, he eventually does find her (noticing that she has boobs even though she's 10 years younger lol) and goes into attack mode, but right before he can do anything to her, he gets immediatly cockblocked by a spark of lightning, everyone returns to 2012!

Everyone is back in 2012! (Mute guy and Blondie are still tied up btw) the massacre continues and we are introduced some new Mahou Shoujos including one that looks like from a 8-bit NES game who can shoot people and skin them like nothing (yikes). Now we see some sort of "zombies" who appeared, apparently they are the people killed by the Mahou Shoujo but I'm not sure. Pervert starts fighting them with a knife (what's with this series and knives) and he manages to kill 2 Mahou Shoujos too, this is a VERY cool scene for Pervert.

Then another Mahou Shoujo appears who looks just like the one Pervert killed and proceeds to kill Pervert!!!! (nooo). We get to see more people getting killed by these girls, you know typical stuff, the team tries to escape, another Mahou Shoujo appears, this one walks like a spider even tho it has just 2 legs and 2 arms, Mute Guy gets killed by this girl when she shoots a ball with a smile face and some spikes on it. Everything seems lost until the army appears! well, more like 2 army people, a big guy and a hot girl (she looks like Mikasa from Shingeki). MC and Blondie get rescued by them.

2 new characters appear, a little girl in a cute pajamas with an animal design and a big guy/girl in a black cloak with a hood and a mask, the brush off the zombies like nothing, say some stuff and then they go.

Now we go to Loli's house (remember this is 2012 again, not the past) she's in a bed receiving medical treatment from her dad, Tits and Bishounen are also there holding hands while in bed. Back to MC, blondie and MC are talking, Blondie starts crying and MC gives her a hug. Back in Loli's house, Loli wakes up and for some reason goes to the roof, her father finds her and she has this evil smirk on her face, she starts saying something.

After that, the army guys + Mc + Blondie go on a mission to save some people from the "zombies", Blondie manages to distract them and then gets attacked by them, she starts crying happily as accepting her death when suddenly all zombies dissapear. The last thing we see is Loli smiling and saying something to her dad in the roof.

At of ch 20, he's alive and kicking. He's also the villain.

So any human can use a Mahou Shoujo stick if you're able to take one from them. So a countermeasure against them is now shown. It also takes me to this other theory that this series could in fact be connected to Sato Kentaro-sensei's other Magical Girl project - Mahou Shoujo Site.

The reason I'm saying this is because...
