 If you liked Kiseijuu |  ...then you might like Tokyo Ghoul |
While watching the anime for this manga Tokyo Ghoul instantly came to mind. To avoid spoilers i'll just say both main characters are in some what similar situation in addition to their personality transition.
Kiseijuu = Parasyte Parasyte and Tokyo Ghoul both involve male protagonists who wake up one day... different... One turned into a ghoul... while the other simply had an alien for an arm. And by alien, I mean a life form that has 100% control of the arm for most of the day. Coexisting and dealing with others who are similar to them, both characters have to live in the same world... with a completely flipped perspective. Tokyo Ghoul is more supernaturalesque/fantasy and more gritty Parasyte is more scifi-ish and psychological Both have action and they are both great reads. Parasyte though is not a bishounen read. It's not

Although the stories are different, Kiseijuu and Tokyo Ghoul shares a familiarity with supernatural horror. The main male protagonist's life changes forever after one faithful day after coming in contact with a supernatural being. And from that experience, they inherit traits that no longer makes them fully human. Throughout both series' perspective stories, the MC struggles to at times to figure out how to deal with his newfound life. At times, they face obstacles but also find new hope. They must also accept who they are as well as realizing the truths/consequences of what they have become. I recommend both series for anyone interested in
after reading both i would say tokyo ghoul is inspired from Parasyte more over i would go ahead and say it is a rip off (tokyo ghoul: re is a different story) -main guy becomes a HALF parasyte/ghoul -there is a Anti parasyte/ghoul police force -both the police force engage in a all out battle against parasyte/ghoul -majority of the parasyte/ghouls get wiped out -both have grotesqueness (limb, head, etc torn into pieces) -endings are a bit different coz tokyo ghoul had to continue....BUT both are GOOD READS

In both, there are male main characters, whose normal lives are interrupted by terrible twist of events. They are both becoming something between a human and a monster, and are struggling with their fate and their own new selves. Kiseijuu and Tokyo Ghoul share a great amount of bloody fights, well done character development and mystery. I would definitely recommend both of them.

While the story of the main characters is slightly different these two are very similar manga and the anime adaptions will also be similar. Both are about a boy who is suddenly met with a strange being in their life and must come to terms with the new abilities that come with this fated meeting. Both feature the struggle of each person's morals and beliefs as they come to accept what they are and use the new abilities they posses to fight a foe. Both are especially violent and gut-wrenching seinen manga with very dark themes and people being split in half and eaten.

The main characters both have to go face hard obstacles and the series are both psychological and the two main characters get put into a hard situation
Both are about an ordinary high school boy who acquires some kind of evil unknown power and wants to get rid of it, until it accepts it at some point. Both have a lot of gory elements as that "evil power" has the tendency to kill people.
Schoolboy suddenly goes from Average Teen to No Longer Human and must cope with being hunted by society as well as a changing set of morals. He must find AND come to terms with his new unique place in the world - he is no longer human, but he still experiences Humanity so he doesn't quite fit in with the Not Humans either. Also there's a load of blood and violence and animal instinct and emotional turmoil followed by emotional numbing all under the everpresent theme of ADAPT OR DIE. Both offer really interesting takes on the place of Humans in the world as a species, but
An ordinary high-school/college student gets turned into a monster by an unfortunate accident; this pretty much mirrors the main plot of these two seinen mangas. Both also deal with how the main characters struggle to preserve their slowly declining senses of humanity as more things happen due to their new nature. While I enjoyed Tokyo Ghoul more, both mangas are nice reads.
Both share similar aspects of the main character undergoing a huge transformation and the struggles of hiding their secret

Tokyo Ghoul obviously took a great deal of inspiration from Parasyte, from the 'monsters' who need to eat humans to survive to the human who becomes part of both worlds (sort of...) though Tokyo Ghoul has more of a culture with its monsters as opposed to Parasyte, where the monsters don't really have time to establish a culture that we see much of.

The basic idea behind the plot is similar. The two main characters have many common features.

Both of the MCs are not completely controlled by the “invasive” species, instead only a part of them is and they share qualities between the invasive species and humans— you could say they are somewhat the bridge between the two. Both MCs experience a similar breakdown in their respective manga after they find out they are the invasive species, and both refuse to kill to satisfy their hunger for humans. Also both Ghouls and Parasites eat humans. Both manga have gore.
