Eisuke Hondou (本堂 瑛祐 Hondō Eisuke) is a character in the manga and anime franchise Detective Conan.
Eisuke Hondou first appeared soon after one of Conan's confrontations with the Black Organization, in which it was revealed that popular newscaster Rena Mizunashi was one of their members. He enlisted into Teitan High School and quickly made friends with Ran Mouri and Sonoko Suzuki, who noticed the striking similarity to Mizunashi.
Some time later, Eisuke visited Ran's father in his office, where he also ran into Conan. After expressing a vivid interest in Mouri's work, he was invited by Ran to come by anytime, much to the displeasure of Conan, who had become suspicious of Eisuke. This suspicion was confirmed by the fact that in subsequent cases Eisuke made several blunders which would 'incidentally' contribute to the solution of the relevant case.
In time, Conan found out that Eisuke was indeed related to Rena Mizunashi. He had come to Tokyo looking for clues of his sister's whereabouts, sparked by him seeing her working as a newscaster by happenstance. He learned the truth from Conan, Hidemi and Shuichi Akai - that his sister, as well as his late father, were working for the CIA against the Black Organization. Following this revelation, he was offered a place in the Witness Protection Program, which he refused, though he decided to follow in his family's footsteps by joining the CIA one day. Alone with Conan, he also confessed that he had fallen in love with Ran and wished to take her with him to America. When Conan protested, Eisuke laughed out loud, stating that Conan's reaction was the final confirmation he had needed: that Conan was really Shinichi Kudo, and that in fact he was responsible for the "Sleeping Kogoro's success." With this revelation, he asked Conan/Shinichi to take good care of Ran in his stead, thus promising to keep his secret.
Eisuke is a person with extremely bad luck. He's constantly bumping into or falling over something. However, his clumsiness belies a sharp intellect and keen talent for observation: With only few clues to work with, he was able to track down his vanished sister to the Haido Central Hospital, where the FBI was keeping her under guard, and even penetrate the facility to confront Rena Mizunashi - who really was his sister Hidemi - before he was discovered by Conan. He figured out that Shinichi and Conan were the same person before even meeting Conan and managed to force to the truth out of him later.
As a person, Eisuke is usually quite jovial and friendly, though very emotional at times; in stressful situations he often lets his feelings get the better of him.

 Clash of Red and Black
While Ran, Sonoko, and Conan visited a friend from Middle School in a hospital, they coincidentally met Eisuke who was looking for his sister who left 10 years ago. His sister looks exactly like Rena Mizunashi but Eisuke insisted that they are different people. To know if they are the same or not, they decided to visit a big fan of hers to confirm it. Koshi Anno, a big fan of Rena, told them that he thinks they're the same person and showed them a video wherein Rena has the same hairstyle as in the picture. But Eisuke insisted that they are different since the video proved that Rena's blood type is AB which can't be possible because when he was a kid, he remembered having blood transfusion from her sister and his blood type is O.
After the winter break, Conan learns from Ran lost contact of Eisuke. The last time that Eisuke talked to her was when he told her that he found a clue on his father's company in Haido Central Hospital, the same hospital wherein Rena was secretly confined. Conan decided to inform Jodie about his suspicions on Eisuke. Jodie told him that Eisuke's father was CIA spy and was killed by Rena four years ago. He later realized that Eisuke found a Black Organization member and is currently in the hospital. The FBI decided to search the Black Organization member hiding in the hospital. While searching in the hospital for clue on Eisuke and the Black Organization, the nurse informed Conan that she remembered Eisuke had a surgery in Tokyo due to his Leukemia.
The night before they decided to move Rena, Eisuke visited Rena's room and forced her to wake up. When he tried to stab her with scissors, Rena stopped him and called him Ei-chan. Conan explained to Eisuke that Rena is his sister and they now have the same blood type, AB, after he had a bone marrow transplant when he was a kid due to Leukemia. Akai told him that her sister is a member of a certain "Organization". Eisuke was then pulled out of the room.
 Suspicious Eisuke
Conan and Haibara meet Ran, Sonoko and Eisuke in a book store. Eisuke remarks that "he probably won't need" a study book the girls are buying, and that he "hates to be restricted by anything; even time." Eisuke visits a karaoke box along with Ran, Sonoko, and Conan. Conan and Haibara notice that a man is trailing the group, and Conan suggests that the man is likely an FBI agent keeping tabs on Eisuke, since he refused access to the Witness Protection Program.
In the karaoke box, Eisuke leaves to visit the bathroom. He takes a very long time to return, and does so with a terrified expression. The body of the man trailing the group is discovered in another room. Conan suspects Eisuke, since he is under the impression that the deceased was tracking him. However, it is soon revealed that the man was in fact a stalker with a fixation on Sonoko. (What had frightened Eisuke was when he mistakenly opened another customer's room, he saw what he mistook as two men kissing.) Ran is very glad that Eisuke is innocent, to the point where her eyes become tearful.
At the ending of the case, Eisuke walks home alone with Conan. He asks Conan to speak with Shinichi about his intentions to marry Ran and live with her in America. Conan angrily tells him that he can't, and reveals his identity as Shinichi Kudo to Eisuke. Eisuke laughs, and informs Conan that he had guessed it all along- showing all his deductions to Conan. He then tells Conan that he will move to America and join the CIA, following in his father and sister's footsteps.
 Plot exposition
 Hints that Eisuke was the biological younger brother of Rena Mizunashi
- They look alike. Both have unique matching eye designs.
- Rena Mizunashi mentioned having a little brother just after the Ding-Dong Dash case. After hearing that the child's mother died, which mirrors her own family situation, she became emotional to the point of crying. Conan noted a similar reaction of Eisuke's later likely meant he wasn't acting.
- Eisuke has a mark on his chest where a needle was inserted to monitor his leukemia. A nurse later revealed that he has leukemia and was given a bone marrow transplant from his sister. Bone marrow transplants change the blood type of the receiver to that of the marrow donor, so Eisuke's blood type changed from type O to type AB. Later his sister was able to donate AB blood to him because of this.
- Hidemi and Eisuke both use the same classical lie detection technique - feeling for the pulse while watching the pupils - which is taught by some American law enforcement agencies.
 Hints that Eisuke was not a member of the Black Organization
- He uses a classical lie detection technique - feeling for the pulse while watching the pupils - which is taught by American agencies. He learned it from his father who was a CIA agent.
- Conan discovered that Ethan Hondou, Eisuke Hondou's father, was a member of "The Company" - a nickname for the CIA. The Black Organization knew Ethan Hondou's real name and that he was a spy. Thus it would be unlikely for them to take Eisuke in because of his family history.
- Eisuke had strong suspicions that Conan was Shinichi evidenced in several questions he asks Kogoro about Conan's activities at crime scenes. Despite this, the Black Organization did not take action against Conan which implies Eisuke and the Organization are not in contact.
