Rantaro

History
Rantaro claimed he came from a very rich family and that he was raised like a celebrity, and that he has multiple younger sisters, most of them stepsisters. Many years ago, he and his entire family went on a boating trip. It was Rantaro's first one. He liked traveling, and once they reached a port, he got off the ship and went on an adventure. His youngest sister followed him off the boat without him realizing and as a result, she disappeared and was never found. Rantaro blamed himself for her disappearance, believing himself to be a terrible older brother and starting to fear that his sisters might hate him.

However, Rantaro was determined to find his sister, and, with his father's permission, he traveled around the world on a boat searching for her, whilst simultaneously helping with his father's business in search of new markets. He firmly believed that his sister was alive unless he was proven otherwise. The traveling was dangerous, especially when he had to cross territories. He gained his Ultimate Adventurer title during one of his journeys through the savanna when he came across a remote village and helped the villager with their research about a rare disease that only affected the people there.

Personality
Rantaro initially is seen a mysterious person and can be later seen as a calm and carefree person, often laughing off insults, trying to get the best out of everyone. He tries to smile often and remain composed, even under potentially dangerous situations. Despite this outwards demeanor, he can get serious quickly, often trying to get answers or what he wants in stressful situations where others would be panicking.

He knows a little more than his friendly exterior lets on, and his actions can often reflect that. When alone, he is reflecting upon himself as to why he cannot remember his talent. He often acts friendly to imitate a 'big brother' of sorts, due to his past and want to be a better brother. He may make jokes often but he means a lot of the words he says. He often has experience in areas of expertise traditionally considered feminine such as cooking and painting nails. He's a family man at heart and is constantly worrying over his large family during all times.

Prologue
After waking up on the U.S.S Monocrow, Rantaro made his way out of his room and meet Peko Pekoyama. They both travelled around together, finding most of the areas were locked off. Eventually they made their way down a set of stairs and decided to stay there until they reached their destination. Peko brought up the E-Handbooks to his attention and they discussed for a bit before hearing voices come from upstairs, soon being introduced to the other ten students on the ship. An announcement played, signaling for the students to head to the elevators, which were broken before. Rantaro didn't like that and still headed up with the group. After they took the elevator, they arrived on an island, more specifically a beach. Rantaro and the group discussed their location and skepticism before deciding to explore and split up. Rantaro and Kyoko made their way to a library where they could have a private discussion. Kyoko questioned him on his demeanor and Ultimate talent, which he admitting to not knowing. He, in turn, questioned her on her talent and why she was so cautious on the cruise. They gave each other their answers, and woke up on the beach afterwards, confusion struck the group as they were just talking with each other. Monocrow introduced himself and the game, handing out the updated E-Handbooks, and tossing a new student onto the beach, Becka Makato, which Rantaro assisted in getting up.

Chapter 1
After the announcement of the game, Rantaro questioned Monocrow about the rules for a while, wanting as much information as possible. He messaged Kyoko through the E-Handbook 2.0's messaging feature and explained that he had a plan. He spoke to Kyoko and Shuichi about how he believed the bird was being controlled by someone on the island, and had Shuichi take him and Kyoko to a large locked door, where they met with Peko. Peko explained she will prevent murder and Rantaro said she shouldn't do it alone. They all decided to head back to the boat after some talking, ending their day there. The next day, Rantaro spends time with Peko, training to use a sword and he picks her brain about her family. He discovers what he believes to be an unhealthy mindset and tries to get Peko to think about it differently, in which he fails and blames himself, thinking of himself as a failure in trying to convince Peko. He meets up with Shuichi and Kyoko later in the day, telling them he trusts them and wants to hear their plan for the motive. He ruffles Shuichi's hair and says he puts his faith in him as he heads off for the boat after the nighttime announcement. Unfortunately, during the night, Rantaro knew what his plan had to be to protect the others. He used poison on himself, killing him on the ocean and making sure no one murders at night.

Peko Pekoyama
Rantaro was first seen talking with her in the prologue, discussing their situation. He spends a little time with Peko on the island, and on the first night he hears Peko talk about her duty of protecting everyone, which he disagreed with, so he told her he was helping. Later on, they practiced sword fighting on the beach, Peko questioning his attitude and Rantaro talking about his family. Later, he meets with Peko in the medical shop and begins training with the sword again, picking her brain about her family and her flawed view of it. He explains his situation as being a failure of brother, in which she reassures him he still has time to rectify that failure. Rantaro keeps questioning Peko on her family views and later forces her out of the building as he tries to convince her she's worth more than the sword she carries. He blames himself as being a bad brother for not being able to help Peko and convince her she's worth more.
