When Kakeru grabbed that skeleton's head, he grabbed it with his left hand as the thumb is on the right side of his hand. And when he slammed the skeleton into the ground, he's using his right hand.
This was okay... I do like female teacher and student doujins and I don't mind a bit of NTR though there's hardly any in here that isn't being imagined by someone. The male teachers may seem like assholes but one's a masochist and one's got a child's sized peen. The female teacher is sexually...
Since the taste of a girl's love nectar varies from other girls... Misaki's love nectar tastes like beef jerkey, Tia's love nectar tastes like fish, Vanille's love nectar tastes like vanilla, Romy's love nectar might actually taste like oil lol
I believe that the naked girl in the last panel is the girl Youta saw when he first traveled to the other world before he met Lumi for the first time. Though I don't know who she is. I came for the ecchiness... but stayed for the story :)
The only thing confusing about this is the time travel aspect of this manga. He was pushed, thrown, and dropped to his death three times by the giant rag doll person who for some reason is Lilia.
I was thinking the girls who don't get the marks are the ones who say they would be happy to mate all day even if they were to die the next day. Both Lilia and Hanahana said something similar.
