"Tacopi no Gensin" is a manga by Taizan5 that has been serialized in "Shonen Jump+" since 2021. At first glance, the genre seems to be a sci-fi human drama about a cute alien and a young girl, but as you read on, it becomes clear that it is a social story with a serious and profound theme.
At the center of the story is Tacopi, a "Happy Alien" who came to Earth, and a girl he meets called "Shizuka-chan (Kinzaka Shizuka)" who has lost her smile. Tacopi tries his best to make Shizuka smile using "happy gadgets," but the serious reality of bullying and abuse at home and school where she is placed is heavier and crueler than he could have imagined.

Theme and appeal of the story
The reason why "Tacopee's Original Sin" continues to attract many readers isthe careful depiction of contrasts such as"goodwill" and, and"innocence" and.
The absurdity and cruelty of human society are highlighted by the way it is written from the perspective of a pure alien named Tacopi. Although Tacopi acts with good intentions, wanting to make people smile, readers will be shocked by the unexpected tragedy that results from his actions.
In addition, this work is based on themes such as "how to face a reality with no hope" and "the cycle of perpetrators and victims," which strengthen the depth and message of the work.
What is particularly noteworthy is that many of the main characters are not portrayed as clearly "bad guys". The bullies also have their own backgrounds and family environments, and the complex human relationships in which everyone is both a victim and a perpetrator evoke realism and empathy.
Furthermore, the characters' psychological descriptions, growth, and emotional fluctuations are depicted very carefully, allowing the viewer to deeply empathize with characters such as Shizuka, Azuma-kun, and Marina.
Exploring the mechanisms of popularity polls and rankings
The reality of official and unofficial polls and surveys
"Tacopi no Gensin"has a relatively short serialization period (2 volumes in total), and despite being a weekly serialization, it has become an explosively popular work. Therefore, there are no popularity polls in Jump magazine or on official SNS (as of June 2025). However, due to the impact of the work and the appeal of the characters, there are many fan-led popularity polls and surveys. For example, unofficial rankings are conducted on the following media and platforms:
| Platforms | Features |
| Ranking.net | The rankings change based on user voting. Comment function available. |
| ankey.io | Real-time voting and social networking available. |
| Personal blogs and YouTube videos | A strong fan perspective, with unique evaluation criteria and introductions to favorite characters. |
These unofficial rankings are characterized by the fact that they allow users to vote freely, so the actual voices of fans are strongly reflected. In addition, characters who left a strong impression in the story, such as "Shizuka-chan" and "Taco-pi", are consistently ranked at the top.
On the other hand, it is necessary to be careful about the reliability of the rankings and the bias of the vote population. In particular, there are cases where well-known characters or characters who made a strong impression in the latter half of the story suddenly rise in popularity due to re-evaluation.
Review trends on SNS and communities
"Tacopi no Gensin" is a work that has received a strong response mainly on SNS (especially X〈old Twitter〉 and YouTube), and the popularity of the characters can also be seen there.

Furthermore, while the evaluations of "Marina" and "Azuma-kun" are divided, they have become a topic of conversation as characters whose perspective changes as the story progresses.
In addition, on YouTube, there are many reviews and ranking videos of "Tacopi's Original Sin", and users are actively discussing the topic in the comments section. There are many opinions based on the overall evaluation of the story, not just the popularity of the characters, such as "happy tools" and "Tacopi's innocence".
Online bulletin boards and fan site communities also have popular discussions every day about the theme of the work, such as "Was there salvation for this character?" and "Who was the one who was most guilty?".
In this way,in social media and online communities, readers' "empathy" and "passion for analysis" have a greater influence on character evaluations than simple popularity polls,and this is one of the factors that form the unique ranking trends of this work.
Tacoppie's Original Sin Top 5 Popular Characters
1st place: Kirasaka Shizuka (Shizuka-chan)
One of the main characters, "Kimusaka Shizuka", is overwhelmingly popular. She is portrayed as a girl who suffers from serious bullying and abuse at home from the beginning of the story, and this struck a chord with readers.
Shizuka's charm lies in the complex emotions hidden in her quiet demeanor and the kindness deep in her heart. At first, she was expressionless and did not show any emotion, but the way she gradually changes her heart through her interactions with Tacopee and the people around her has evoked sympathy and emotion from many readers.
Shizuka also embodies the keyword "original sin" in the work. The pain and sin she carries and how she accepts it are the axis of the story, which makes her popularity unshakable.
Second place: Tacopi
Tacopi, who came from Happy Planet, is the narrator of the story and the purest being. A cute octopus-like creature, his bright and cheerful speech and his brave attitude of trying to make people happy with his "happy gadgets" have captivated many fans.
But Tacopee's charm doesn't end there. The tragedies caused by his "ignorant goodwill" and the way he learns, suffers, and changes through his mistakes strike a deep chord in the hearts of readers.
Tacopee is highly regarded as the most multifaceted and philosophical being, and is ranked a respectable second place, as it cannot be described simply as "cute."
3rd place: Marina Kuze
Ranked third is another main character, Marina Kuze. She appears as the one who bullies Shizuka, but the background to this is deeply related to her mother's lack of love and problems in her home environment.
Marina's charm lies in her duality as both a perpetrator and a victim. At first, she is portrayed as a repulsive character, but as the story progresses, her inner self is revealed and the reader realizes that she is "the weakest and loneliest child of all."
Marina is a very impressive character who shakes the reader's sense of ethics, asking questions such as "is it forgiven?" and "is punishment necessary?"
4th place: Azuma-kun
Azuma-kun, ranked 4th, is depicted as one of Shizuka's few allies. He treats Shizuka kindly, worries about her, and has the sincerity and courage to try to help her in his own way.
However, Azuma-kun is not a completely "good person" either. He was tormented by his own powerlessness, and a certain action led him to carry a heavy cross, which shocked many readers.
The charm of Higashi-kun is his strength of heart that cares for others despite his weaknesses. There are many comments on social media saying, "I hope he gets his comeuppance" and "I hope he gets saved," so he can be said to be the second most sympathetic character after Shizuka.
5th place: Chappie
Chappie is the dog owned by Shizuka Kirasaka, and has been a part of her life since the beginning of the story.Although he doesn't appear in many scenes, he is very memorable to readers and is depicted as a character that symbolizes Shizuka's feelings and family environment.
Shizuka is depicted sleeping with Chappie and hugging him, and she pours out her deep affection for him. For her, who has lost her smile at school and at home and cannot open up to anyone, Chappie is the only person she can safely entrust her emotions to, and he has a very large meaning as "someone who will gently accept the feelings that she cannot express to anyone".
For readers, Chappie is a symbol of innocent love, and is an important character that shows that Shizuka still has a faint trace of "kindness" and "warmth as a person" deep in her heart.
Also, the appearance of Chappie makes Shizuka's "loneliness and hope" more realistic, and the changes she undergoes as a result of meeting Tacopee more convincing.
Introducing other notable characters
Important supporting characters and highlights
While the main characters make a strong impression in "Tacopi no Gensin," the supporting characters also play an important role in deepening the depth of the story. Here, we will introduce characters who did not make it into the TOP 5 but left an impression on many readers.
Shizuka Kirisaka's Mother
Her mother is at the center of Shizuka's family problems. On the surface, she appears to be a dedicated and meticulous person, but in reality, she is portrayed as a cold-hearted person who repeatedly abuses Shizuka mentally and physically.
Her presence makes Shizuka's suffering and despair more profound, and highlights the plot where Tacopee's good intentions go awry. Despite being a mother, she is a character who draws out strong emotions from readers and is seen as "the greatest evil in this work."
Nagase Junya (Marina's father)
Marina's father,Nagase Junya, is also a character who has a great influence behind the scenes of the story. On the surface, he seems to care about his daughter,but his true nature is his selfishness that doesn't care about his family and his irresponsibility in entrusting excessive child-rearing to his mother.
His indifference and neglect led to Marina's personality development and her mother's mental breakdown,and he makes us think that turning a blind eye is the deepest sin.
Teachers and other adults around the school
What is striking throughout the story is the "helplessness" and "indifference" of teachers and other adults around the school.They are often depicted turning a blind eye to bullying and abnormal situations occurring among children.
This makes the story not just about children's problems, but a deeper story that includes criticism and questions of the social structure itself.
Summary
"Tacopi no Gensin" is a work that is attractive for its shocking development that is contrary to its appearance and its deep human drama, and is a masterpiece that is deeply engraved in the hearts of many readers. The characters that appear have complex and multifaceted backgrounds and psychological descriptions that go beyond the simple framework of good and evil, and every time you read it you will be reminded of something new.
In particular, the characters ranked in the top 5 most popular characters not only play a central role in the story, but are also always at the center of discussion as the subject of readers' sympathy, conflict, and discussion. It is impressive that characters such as Shizuka-chan, Tacopee, Marina, Azuma-kun, and Chappie are very popular on social media and unofficial survey sites, and each of them has strong support.
In addition, characters and adults not on the ranking are also important pieces that make up the story in three dimensions, and they play a role in delving deeper into the questions of the work's themes, such as "sin and forgiveness," "kindness and violence," and "what is happiness?"
