Ryoma Takebayashi (竹林 竜馬, Takebayashi Ryōma) is the main protagonist of the series.

Appearance[edit | edit source]

In his former appearance, he looks like a muscular man with slightly better then average height, but his current appearance is average with a gentle aura after the modification by the goddess Rurutia.

In the manga and Reboot novel illustrations, he has dark-brown hair and brown eyes.

Personality[edit | edit source]

Ryoma is a kind person who cares for others when they need help.

History[edit | edit source]

Ryoma was a lonely man who led a life filled with hardships until he died from an unfortunate accident during his sleep.. In the afterlife, he is greeted by three gods who grew fond of him and send him to another world as a child,where he makes use of his innate knowledge and abilities,combined with the gods' blessings to live a new life filled with challenges and happy meetings.

Background[edit | edit source]

Ryoma was a 39-year-old man from Earth, Japan. He died from blood loss after he sneezed four times and hit his head on the ground. He was reincarnated as an 8 year old boy in another world, in which he could use magic given to him by three major gods; Gyan, Kufo and Rurutia.

Before he reincarnated, he had hobbies like watching anime, playing games, and reading manga and light novels. His life could be described as extremely plain (or in another sense, tragic), He was overloaded with work, and to himself, perhaps without any purpose, as indicated when he wasn't surprised nor saddened after his own death. He had never experienced a romantic relationship. He practiced meditation every day and had been trained in different martial arts from a young age. After he was reincarnated into the fantasy world, he kept all of the skills he accumulated from his previous life on Earth.

Some became Huge/Big slimes (a group of 100+ slimes of the same type combined) and some King slimes (a group of 1000+ slimes of the same type combined).

All slimes are capable of absorbing mana. Some slimes can evolve twice (ex. regular slime > poison slime > medicine slime).

Ryouma takes the monster affinity exam in Ch 139 and finds out that he has an affinity for monsters that flock together (like some birds), or gather in groups (like slimes or horses). The taming condition could also be 'fecundity', which has something to do with the reproductive potential of the monsters. The number of monsters that have high fecundity would be lower than those that 'flock together', so we will probably learn more about his taming conditions after he contracts more monsters.

  • Regular slimes (slimes that haven't evolved) - Ryouma usually has a couple on hand at any point of time for research purposes on slime evolution.
    • A monster that can be found anywhere. It is considered the weakest monster. It is omnivorous and its body has an average diameter of 20 centimeters. Its jelly-like body houses a nucleus, which when destroyed, kills the slime. Upon death, the slime’s body vanishes into nothingness. it is a mysterious creature, to say the least.
    • Skills: Digest Lv 2, Absorb Lv 3, Split Lv 1
  • Acid slimes x 666

    • Skills: Sticky Liquid Lv 5, Sticky String Shot Lv 2, Physical Attack Resist Lv 1, Hardening Lv 3, Jump Lv 3, Absorb Lv 3, Digest Lv 3, Split Lv 3, Staff Mastery Lv 1
    • Research results:
      • Ryouma frequently uses the sticky slimes as fly/bug traps by sticking them in corners of the room to catch and eat bugs.
      • The sticky liquid produced by these slimes can be applied to cloth in order to waterproof it. Ryouma and the Morgan Company (Serge-san) build a warehouse for the production of the waterproof clothes in order to keep up with demand. The production of these clothes requires humans for setting up the racks, supervising the drying process, and delivering the clothes too and from the warehouse. The sticky slimes, and a few monster tamers employed by Ryouma, are able to apply the liquid by themselves.
      • Ryouma is able to mass produce spools of sticky slime thread, a strong thread typically used for sewing, by buying several spinning wheels and teaching the slimes how to turn the wheel and spool the thread themselves.
      • Used the hardened sticky slime fluid, Ryouma can create a cloth with the same protective capacity as chain mail. It can be worn under regular clothes, is sufficiently comfortable, and is extremely resistant to be cut or pierced by sharp blades; though you will still experience the blunt force impact. It can be cut and sewn together like regular cloth, but the blacksmith has to use special scissors in order to cut it because of how durable the cloth is.
  • ^Scavenger slimes x 3033
    • Ryouma wasn’t happy with the fumes coming out from the toilet and the garbage inside the cave, so when he remembered how some slimes showed interest toward rotting corpses, he caught a new batch of slimes and threw them at the toilet and the garbage. As a result, the slimes evolved into scavenger slimes. These slimes eat garbage and turn them into fertilizer. A special trait of this variation is that they are able to reproduce more rapidly compared to other variants.
    • Prefers earth and darkness attribute mana.
    • Skills: Disease Resist Lv 7, Poison Resist Lv 7, Lead Belly Lv 6, Clean Lv 7, Deodorize Lv 7, Deodorizing Agent Lv 5, Stench Lv 6, Produce Fertilizer Lv 5, Physical Attack Resist Lv 1, Jump Lv 3, Digest Lv 7, Absorb Lv 3, Split Lv 6, Martial Arts Lv 1
    • Research results:
      • Because these slimes can eat garbage, Ryouma proposes a plan to start a garbage disposal system centered around employing scavenger slimes and a few monster tamers to handle all of the excess garbage produced by the city of Gimuru. (Ch 158)
      • Ryouma proposes selling the fertilizer produced by the scavenger slimes, as it is a very good substitute for magic fertilizers, would be much less expensive to produce, and could be used in producing better crops more quickly. (Ch 158)
      • Ryouma is capable of mass producing Running Mash (mushrooms that being monsterified) by cultivating them using scavenger slime fertilizer. He is currently researching ways to cultivate mushrooms w/o monsterifying them. (Ch 158)
  • ^Cleaner slimes x 54
    • Slimes frequently drink water, but there are some who prefer to drink the water from Ryouma’s bath. Thinking it wouldn’t harm them, Ryouma allowed these slimes to drink as they pleased. In the end, they evolved into cleaner slimes.
    • Capable of eating grime and filth, typically used for cleaning clothes, dishes, dirt, etc.
    • Prefers water and light attribute mana.
    • Skills: Clean Lv 4, Deodorize Lv 8, Deodorizing Liquid Lv 6, Poison Resist Lv 5, Disease Resist Lv 5, Physical Attack Resist Lv 1, Sweeping Lv 1
    • Research results:
      • Ryouma started a laundromat business chain (Bamboo Forest) by using the cleaner slimes to eat the filth/grime/dirt/blood off of clothes, and charging customers a small fee based on the size of bag used (7-pair, 14-pair, 30-pair). Currently has 2 shops, and is preparing to open more (Ch 158).
      • Because they eat just filth, you can stick your hand inside of them without being injured. If you ask them to clean your body, they will remove all the waste attached to the body, including dead skin. They can also prevent pimples from forming by removing the sebum clogging the pores. Using the cleaner slime in this way results in the improvement of the skin, and has beautifying effects.
      • The slime can be used to correct writing errors (typos) on a document. They are capable of cleaning the 'dirty paper' and turning it into 'clean paper'. They can clean the entire sheet of paper, or just focus on a small section by using a tentacle to touch just the area that needs to be cleaned.

      • Medicine Tonic - A liquid that reacts with the mana inside a medicine to strengthen the efficacy of the medicine. Should be used in moderation, since some medicines can become poisonous if they are too strong.
  • ^Deodorant Slime x 2 (Ch 90) - Evolves from a Cleaner slime that consumed charcoal.
    • Capable of using several skills that absorb or eliminate odors. Can produce liquids that absorb or eliminate odors, which can be used by people other than the slime itself. Can produce an irritating stench in both gaseous and liquid form, and produce a defensive barrier that suppresses the smell and prevents it from latching on to other things.
    • Eats charcoal and dirt.
    • Preferred mana?
    • Skills: Absorb Odor Lv 8, Extract Odor Component Lv 6, Erase Odor Component Lv 8, Odor Defense Lv 5, Stench Lv 2, Irritating Stench Lv 2, Odor Absorbing Liquid Lv 7, Odor Component Extraction Liquid Lv 5, Odor Component Eraser Liquid Lv 7, Odor Defensive Liquid Lv 4, Liquid Stench Lv 1, Irritating Liquid Stench Lv 1, Disease Resistance Lv 5, Poison Resistance Lv 5, Physical Attack Resistance Lv 1, Clean Lv 4, Sweeping Lv 1, Jump Lv 3, Split Lv 1
      • The Absorb Odor skill absorbs odor from the air.
      • The Extract Odor Component skill absorbs odor from an object that the slime is in contact with.
      • The Erase Odor Component skill literally erases the stench, and the Odor Defense skill suppresses the smell and prevents it from latching onto others.
      • The Stench skill works just like the Scavenger slime’s, wherein it releases a foul odor. The Irritating Stench skill also releases a foul smell, but it’s more irritating. It’s not poisonous, it’s just that the odor released is so strong that it’s able to cause one to tear up, so it’s a skill that needs to be handled with care. The Irritating Stench skill has the potential to become as effective as a tear-gas grenade. The liquid variants of the skills just means that the slime releases the skill in liquid form instead of gas. The liquids are all black and sticky, similar to mud.
      • Unfortunately, using the Deodorant slime’s Odor Component Erasure Liquid like the Cleaner slime's Deodorizing Liquid results in the target object being stained with black. Which it makes it difficult to use as a deodorizing agent for laundry. But the Odor Component Erasure Liquid of the Deodorant Slime has a special trait which allows it to be diluted when placed atop a person’s hand or mix with other liquids. This is a unique trait that the cleaner slime’s deodorizing liquid doesn’t have.

    • Despite their high split rate, there aren't a lot of them in the wild. This is due to a few reasons; the first is that Fluff slimes do spread just like dandelion fluff when splitting, but not all of the fluffs become a Fluff slime. The second reason is that nearby villages may find them annoying and request that they be exterminated.

Look like whichever mushrooms they were produced from, in addition to having sharp-looking nails and protruded feet.

Etymology[edit | edit source]

  • The name Ryoma means "dragon" (竜) (ryo) and "horse" (馬) (ma).
  • Ryoma's surname Takebayashi means "bamboo" (竹) (take) and "forest" (林) (hayashi/bayashi).

Trivia[edit | edit source]

  • On Earth, Ryoma had experienced harsh living conditions and endured endless training from his father from a young age.
  • Ryoma states that he has pulled carriages while running lined up with a horse.
  • Ryoma hunted pigeons in the park to survive.
  • Ryoma's father was often violent and beat him up.
  • Ryoma's parents passed away from different deaths:
    • His father died due to smithing.
    • His mother died from overworking.
  • In the novel Ryoma doesn't rely on help from others when he deems it unnecessary and instead does it all himself. Like when he was building the store he worked on it alone for 10days, only relying on Serge to supply the materials to him.
  • The God of Water and Fishing, Sereriputa, Manipulated Ryoma's Soul to find out the truth as to why the Earth God gave Ryoma so many God Trials in his past life. Manipulation of a living soul is something very close to a Taboo for Gods due to the fact that souls that have been "fiddled with" by the gods can never enter the cycle of Reincarnation.
  • The God of Earth treated his life as a Video Game Character and built him with a predisposition for mass murder and intended for him to crack under pressure (provided by God Trials) and go on a mass killing spree. when this did not happen Earth God killed him to reset and try again. (CH 211.3)
