Beans (ビーンズ, Bīnzu) is the Hunter Association Chairman's personal secretary and helps in organizing various things that the Hunters Association is involved.
Beans has a bean-like appearance, and is nose-less. It is unknown whether he's a human or not. He has pink skin in the 1999 anime and green skin in the 2011 anime, and is short in stature. He is always seen wearing a black tuxedo.
Beans appears as a duty-bound person, who also puts a lot of dedication and even enthusiasm in the (many) errands he runs for the Hunters Association. He was very loyal to former chairman Isaac Netero, and agreed to trick the Zodiacs to carry on his will.
Hunter Exam arc
As soon as Gon, Kurapika, and Leorio arrive at the 287th Hunter Examination site in Zaban City, Beans gives them their respective number badges. Beans tries to reason with Menchi for her to reconsider failing all of the examinees, but fails. Consulting the situation over with chairman Netero; Netero decides to personally try and reason with Menchi in person. After the retake of the 2nd phase of the exam, Beans announces to the examinees within the official Hunter Association Airship, information about the 3rd phase of the exam and they're free to do what they wish in the meantime. On the 3rd phase site, Beans briefly explains the rules to the examinees and takes his leave within the airship.
Beans enjoys a meal with all of the Examiners and Netero, after the 4th phase of the Exam. Menchi inquires what Netero's age during the meal and Beans informs her he's about 100, but has been told that for the 20 years he's worked with him. A curious Menchi and Buhara ask Netero what he has in store for the final phase; Netero divulges he's found a new wrinkle of sort and going to interview the examinees. Confused Menchi asks Beans what Netero means, but Beans can't figure it out, and they should brace themselves for whatever it is. So Beans makes a special announcement to the remaining examinees that they'll all be interviewed by Netero, starting with Hisoka. After completing his interviews Netero creates a chart and shows it to Beans and the Examiners, all of whom are shocked by Netero's plan for the final phase.
Beans could be seen attending the final phase of the Hunter Exam and again in the debate held after the final phase of the exam with the examinees and examiners. When the debate was over Beans informs the new generation of Hunters the perks and uses of their new Hunter Licenses.
Chimera Ant arc
By the end of the Chimera Ant arc, Beans is contacted by Morel Mackernasey about what occurred at the end of the Chimera Ant Extermination mission. Although Beans was skeptical about trusting Palm overseeing the Chimera Ant King's death, Morel retorts the difference between those who work in the Hunter Association and those who don't. Beans claims Morel's logic won't fly with Vice Chairman's associates so he should be ready to be subjected to a hearing and hangs up the phone. From a secret safe in his office, Beans takes out a DVD and uploads its content to the internet. Morose Beans thanks the chairman for what he's done and wishes he rest in peace.
13th Hunter Chairman Election arc
Following Netero's death, the Zodiacs summon Beans pick a lottery of 12 papers, each one with the name and set of rules of the Zodiacs out of a bucket. Bewildered the Zodiacs chose him to pick the winning lottery, looks at the Boar Ging, who looks back at him. So Beans pulls a lottery from the basket and it's Ging's. Beans then reads off Ging's rules 1-5. Hearing the rules and the restrictions to them, the Rat Pariston agrees to concede to rules 1-4, but proposes that the 5 rule should be decided in the future. Ging agrees to it aggravating the Zodiacs, while baffling Beans. It's revealed two days before the Zodiacs arrival at the Hunter Association, Ging visits Beans and immediately asks if particular items in his room are also in the Zodiac meeting room. However Beans informs Ging they're already in the meeting room, so Ging writes down a set of rules and shows them to Beans.
Beans reads over the rules and Ging informs Beans of his prediction of everything that will take place in the following days and why they'll most likely choose him to pull the lottery. Ging instructs Beans if he agrees with his set of rules then to fold it a certain way and to hold onto it until the day comes, but also instructs if it doesn't go as planed then burn the paper. Beans anxiously agrees to follow Ging's instructions and is in favor of him becoming the next chairman. Ging rejects the idea of becoming Chairman and merely wishes to succeed the Chairman's Legacy. Curious about rule 5, Beans asks about it and Ging details it's a compromise to make the other Zodiacs concede to the other rules, but if it does pass he'll step down. Nervously Beans inquires, why Ging would he go through all of this if the results don't matter to him. Ging claims if his target moves the way he planned it, then it's more fun that way.
After the First Election for the 13th Hunter Chairman was held, Ging shows frustration over Beans refusal to show him the results of the election as he was chosen to be the executive chief of voting and insults him. Sometime after the Second Election for the 13th Hunter Chairman, Beans reminiscences about why Netero chose Pariston as his vice-chairman. Though as much as Beans respected the chairman, he admits that his decision to make Pariston his 2nd in command was a mistake. A meeting is held by the Zodiacs with Beans, concerning the increase in number of absentees in the Third Election for the 13th Hunter Chairman. Since it was decided that Hunters who fail to vote in the election twice will have their Hunter Licenses revoked. Beans gives the Chicken Cluck a list of Hunters who have to turn in their Hunter Licenses to the Hunter Association HQ and provide an explanation for their absence.
Via broadcast, Beans announces the current 16 candidates and their respective Hunter occupations. Beans is indirectly mentioned when the Dog Cheadle confronts Ging inquiring why he's leaving the next day. Ging frustrated by Beans divulging such information to Cheadle and claims he'll never tell him anything again. When Gon returns to the Hunter Association auditorium to meet his Dad; Beans informs him that he's waiting for him at the World Tree.
Dark Continent Expedition arc
A panic stricken Beans interrupts the Zodiacs meeting to show them an announcement video by the Kakin Kingdom's King Nasubi Hui Guo Rou about a controversial and ambitious expedition to the Dark Continent lead by Netero's son Beyond Netero. After the video Beans confesses that Netero left 2 CDS instead of one and the other DVD was to be watched by the Zodiacs if anyone came forward claiming to be his child after he died. Immediately after the Zodiacs watch the DVD Mizaistom questions Beans if the chairman had any other final requests, but Beans quickly denies he did. As the Zodiacs discuss how to approach the situation at hand, Beans answers a phone call and it's none other than Beyond Netero himself. Later Beyond, the Zodiacs, and Beans all meet together and Beyond greets Beans and requests he contact the V5 and inform them, Beyond Netero has been captured.
- Since no name had been given to Beans at the time, the 1999 anime series called him "Maamen", which could be a pun based on "mame", the Japanese word for "bean".
