Manga Review | Playboy Beast by Minomushi Momonoki
Title: Playboy Beast
The world has evolved. Through various human experimentation, a second species of human has been created through a mixture of animal and human DNA: demi-beasts. Unlike pure humans, demi-beasts undergo animalistic breeding periods known as heats once they reach puberty. Males long to impregnate females, while females want to be impregnated by males. Unfortunately, for panther demi-beast Riku, though he’s long since passed the age of puberty, he’s yet to have his first heat.
It’s not that big of a deal, but as Riku gets older, it becomes more and more concerning, especially when female demi-beasts begin approaching him. Desperate to initiate a heat, Riku ends up dating a fox demi-beast female, hoping to coax out his sexual urges by going on dates with her, but no matter how hot she might be, he just doesn’t feel compelled to go into heat. Things only become more complicated and frustrating when Riku’s living situation changes. He ends up being roomed with an albino lion demi-beast named Touma.
While Touma initially appears to be a run-of-the-mill book nerd, he turns out to be a bit more of a delinquent. Touma sneaks off campus overnight and has a casual sexual relationship with the school nurse. He’s everything Riku wishes he could be, or so he thinks. After Touma finds out about Riku’s perpetual virginity, Touma is all too happy to toy with Riku’s innocence and get Riku’s heat started. As it turns out, Touma isn’t everything Riku wants to be, but everything that Riku wants.
Manhwa Review | Stage of the Dark Souls by Guacamole
Title: Stage of the Dark Souls
Mihael is a devil that lives among humans. Though he shouldn’t, he ends up falling in love with a particular human, a man named Adonel Schravant. He is particularly in love with his stunning soul, which Mihael desperately wants for himself. Unfortunately, no matter how hard he tries, Adonel is always being swept away by other humans. Unwilling to share Adonel anymore, Mihael goes to the clergy and tells them that Adonel’s family is practicing pagan worship, which leads to their execution. Alone and desperate, Adonel is ripe for the picking, so Mihael makes him an offer he knows Adonel can’t refuse: Mihael will tie himself to the Schravant line, granting them all of his powers. In exchange, once the Schravant has fallen in love with Mihael and willingly given his soul, Mihael will take it, and they will be bound for eternity.
So Mihael lives in Adonel’s shadow, helping rebuild the fallen Schravant name. All the while, Adonel has a child, despite Mihael’s hate over it, and grows to a ripe old age. Finally, at the end of Adonel’s life, Mihael broaches the subject of Adonel handing over his soul. Only then does Adonel reveal that he never loved Mihael and would not give up his soul, meaning Mihael would remain tied to the Schravant bloodline until he can convince another descendent to fall in love with him and willingly give their soul to him. Mihael is devastated but far from willing to give up.
Three hundred years later, after the death of the head of the Schravant conglomerate, Mihael finds his two sons: the firstborn, Evan, and the second, Victor. Mihael has been watching over the family all this time, biding his time and waiting for the ideal soul. Finally, after all this time, Mihael has found it. Two of them, in fact, and he isn’t willing to give either of them up. One way or another, he will make them fall for him and then take their souls, but not until he destroys them from the inside out.
