Masayuki Rudra Nam Ul Nasca

Masayuki Honjou (本城正幸) is a Japanese Stray Otherworlder and an adventurer.

Due to the effects of his Unique Skill Chosen One he was deemed a Hero against his will. During Rimuru City's Capital Opening Festival he got acquainted with Demon Lord Rimuru and later became his subordinate, taking the role of Tempest's spokesperson for adventurers and advisor for the Labyrinth.

Personality
When he was under pressure to act out the role of Hero, Masayuki acted confident, but felt very timid on the inside. After gaining the backing of Rimuru and no longer feeling like he is under pressure he became much more self-assured and able to speak his mind again. While he keeps his Modern Japanese speaking patters, using the "-san" honorific for everyone, he lacks proactiveness and tends to always go along with the flow of events, unless it involves something that he recognizes as Otaku matters like the Labyrinth, in which case he becomes a very involved party.

Background
One Day, while walking home from school with his multitudes of friends, Masayuki saw a "Nordic Beauty" standing on the street, upon which he suddenly got transferred to a different world where he unexpectedly obtained the Unique Skill The Chosen One, which made all the people in his surroundings spontaneously admire him. Masayuki's only fighting ability is the little bit of hobby-level Kendou he had learned, but the crowd considered him an invincible Hero, due to him being unable to control his Unique Skill's effects. For various reasons, such as fearing the possibility that the crowd could turn against him if they got convinced that he is just a "fake Hero," or that those who lost against him in spars would be dishonored for life if they found out how weak he is, he decided he could only go along with their claims and play the role of Hero.

During those days seemingly the only one up to this point who was unaffected was the Free Guild's Grandmaster Yuuki Kagurazaka who he could have a normal discussion with, especially as fellow Otherworlders, however since Yuuki was always busy with his job, opportunities to meet up were fairly rare and Masayuki didn't want to rely on Yuuki too much. But due to these events, Masayuki became an adventurer and obtained two companions -- the adventurer Jinrai, one of the first people Masayuki met in this world who Masayuki also defeated via his luck in a battle; and Bernie, an Otherworlder from the USA who became a magician. Thanks to the luck and buffs of Masayuki's Unique Skill, the party easily crushed all adversities they've encountered.

At one point, the flow of events led Masayuki into participating in the Ingrassia Arena tournaments, winning all matches easily, all thanks to the effects of The Chosen One and the party's abilities. This raised his and his party's prestige even further.

The party got it's fourth member when Jiu, a Spirit Magician, heard the rumors about Masayuki and met him to check the validity of them. At first she voiced that he's a fake, but she eventually came around to accept and later even worship him, and so the party of four was complete. Together they advanced through the ranks until they eventually became a Rank A party.

Monster Capital Opening Festival arc
Upon request by Yuuki, Masayuki's party went to the small nation Balakia that is bordering Ingrassia in order to deal with a slave trading ring suspected to cooperate with the nation its housed in. Thanks to Masayuki's The Chosen One the conspiracy was easily resolved, and the slave traders successfully taken down. However it turned out that the slave trading organization Orthrus not only enslaved humans and wild beasts, but also elves, who upon being freed requested to return to the Great Jura Forest. Despite worries how Demon Lord Rimuru would react about the elves having been enslaved, the party decided to escort the elves back to the forest.

Upon their arrival in Tempest, after a series of events, it was decided that the party would participate in the Tournament held in Rimuru City and if one among the party won the Championship, they'd be granted the right to challenge Rimuru in battle. After easily passing the preliminaries, Masayuki's enemy was his party member Jinrai in the Quarter Finals. Jinrai just forfeited the match. In the Semi-Finals Masayuki had to face Gozurl who he managed to convince to forfeit via his Unique Skill's effect as well. In the finals Masayuki faced Gobta who had obtained a Unique Skill of his own on that very day and thus was able to resist the effects of Masayuki's The Chosen One. However due to Gobta not having properly tested his new fusion ability with Ranga, Gobta ended up crashing himself into a wall and knocking himself out from the shock of what happened. Afraid that he might actually end up having to fight against Demon Lord Rimuru, Masayuki chose to forfeit the match despite being the winner, hence Gobta won the Championship instead.

Later, upon being invited to dinner by Rimuru, Masayuki reluctantly agreed. After introducing himself Rimuru revealed that he is an Otherworlder from Japan as well. After their discussion, Masayuki decides to join Rimuru as his subordinate, mainly working to promote Tempest to adventurers. Then he cooperated with Rimuru in the unveiling and public test-run of the Labyrinth.

Majin Behind The Scenes arc
When Masayuki offered suggestions toward rest-spots and save-points for the Labyrinth, Masayuki's range of duties expanded to also include him as a de-facto adviser for Labyrinth matters.

Eastern Empire Invasion Arc
Rimuru appointed him as the commander for the Volunteer Corps against his will. Since this particular corps consists of predominantly humans, it could raise unwanted discontent if a monster was appointed as its commander. Masayuki was reluctant to take the position, but nonetheless relented when Rimuru brought up the favors he owed.

Trivia

 * Masayuki's entire shtick is very similar to King in One Punch Man -- both of them are ordinary humans heralded as invincible heroes against their will. Furthermore, they always manage to get out of sticky situations due to other people's always positive (mis)intepretations and their incredible luck.
