Sotaru, a single 37-year-old
man from Tokyo with a steady job, was invited
out by Tamura, a coworker so that he could introduce
him to his fiancée. A random attacker with a knife
charged toward Tamura and his fiancée shortly after they
had first met on the streets. Sotaru steps between them
to protect them, but when he does so, he gets stabbed. Sotaru notices that his wound
is almost certainly fatal as the attacker flees the scene. Sotaru keeps hearing a strange
voice in his head that is analyzi
ng his thoughts and
forming abilities by his current desires while Tamura
is pleading for assistance. Sotaru concludes by wishing
Tamura and his future wife all the best and requesting
that he destroy his hard drive so that no one can
discover what is stored on it. Sotaru is left alone with his
thoughts as the world around him fades, and it takes him
some time to realize that he is in a different body. He discovers after some
testing that he died and was reborn as a slime. The same voice that pr
eviously
identified itself as his special talent "The great
sage," who can quickly analyze and process information for
him, reappears in his head as he is thinking to himself. It already has a significant
amount of knowledge in addition to that. Sotaru receives instructions
from the great sage on how to use his new
body and his abilities. Sotaru starts soaking up
everything interesting he finds inside the cave
he is in after realizing that he can essentially
devour and store anything inside his
slime body. He meets a dragon who
just so happens to be imprisoned in the same
cave as he is doing this. To properly see as slime,
the dragon teaches him to sense magic all around him. The dragon identifies
himself as Veldora Tempest, a storm dragon, once
Sotaru can see clearly. Veldora explains how he has
been sealed here for 300 years during their conversation. He makes Sotaru feel bad. He suggests becoming
friends with Veldora because he is aware of how
lonely it can be, and the dragon hesita
ntly agrees. Sotaru decides to assist
Veldora in escaping the spell of limitless imprisonment that
is keeping him imprisoned. He, therefore, asks the wise
man for any suggestions. with the sage's
extensive knowledge. The great sage offers Veldora
a solution to set him free. Being devoured by Rimuru's
special predator ability to allow the great sage to
examine the seal from within. Before Sotaru devours him,
Veldora gives him the name Rimuru because in this world
he was just a slime without a nam
e and instructs him to
think of a shared family name. They become Rimuru and
Veldora Tempest after Rimuru chooses the name "tempest." The analysis of the endless
imprisonment is then started as he eats Veldora. The world experienced
a significant tremor as Veldora, a storm dragon,
vanished in Blumund's kingdom. To maintain the security of
the kingdom, the minister baron Velyard requests
that the guild master fuse investigate this issue. Fuze decides to send an
expedition to investigate it. Weeks
went by as Rimuru
continued to explore the vast network of caves, eating any
dangerous creatures he came across and learning their
skills by using predators. He eventually locates
the cave's exit, but a huge gate is blocking it. Just as he is attempting
to find a way to pass. Three humans from a small
adventuring group walk through the gate as it opens. Rimuru stays hidden until
they go deeper inside the cave, at which point
he takes the opportunity to escape and emerge in
the vast Jura Forest.
He doesn't travel very far
before coming across a group of goblins who have come to
him for help after sensing his overwhelming presence. He is introduced to
the village elder after being taken to their
village, who informs him of the circumstances. Their god reportedly
vanished about a month ago, and ever since,
numerous vicious monsters have been harassing them. Rimuru feels responsible
for the situation because this time exactly
matches the moment that he devoured Veldora. The village elder
informs
Rimuru of the dire wolves that frequently attack them and
recently killed their most stalwart warrior, putting
the village in danger. The elder offers Rimuru the
loyalty of the goblins in exchange for his protection
against the dire wolves. The dire wolves howl as they
prepare to attack as Rimuru mulls over the predicament. The goblins begin to panic,
but Rimuru calms them by promising to grant their
wish in place of Veldora. recognizing that the
village's real defenses have been destroy
ed. Before getting the injured
goblins organized to build the village fence,
Rimuru heals them first. Once night falls, the
dire wolves attack, but they are stopped by the
goblins' established defenses and Rimuru. The dire wolves' pack leader
attacks Rimuru, but he is quickly dispatched by him. By devouring their pack
leader and intimidating the remaining dire wolves with
his physique and abilities, he hopes to scatter them. However, the rest of
the pack yields to him rather than flee. Rimuru or
ders the goblins
and dire wolves to cooperate going forward to strengthen
and secure their village. He quickly realizes that
giving the goblins names is impractical, so he gives the
elder goblin the name Rigur and his son the name Rigurd. While he's at it, he
also decides to give the village's goblins names. As soon as he has finished
with the goblins, Rimuru starts naming the dire wolves,
first giving Ranga to the son of the pack leader he killed. As soon as the great sage
gives him the name an
d warns him that his magical
reserves are getting low, his body shuts down, putting
him to sleep for three days. Rimuru discovers that
naming monsters is difficult because it takes a lot of
magical energy to do so. When Rimuru awakens three
days later, he is horrified to see how the goblins and
dire wolves have changed. Meanwhile, Rigurd explains
that everything is because of the names he gave them. Observing that all the
dire wolves evolved even though he only named
Ranga, the monster evolved a
fter being given a name. He is asked by Rimuru
how that came about. Ranga informs him that
the dire wolves have come together as a pack and
have evolved into tempest wolves because of Rimuru. In his speech, Rimuru lays
out the guidelines for the village and reveals his
ideas for its future growth. Sumi notices that the
goblins lack the knowledge necessary to construct
homes or sew clothing. He is told by Rigurd
that there are Dwargonian dwarves who are adept
at doing this sort of thing and that
they have
previously traded with them. After learning that, Rimuru
sends Ranga to speak with dwarven craftsmen while
bringing a small group of goblins and wolves. Gobta, a goblin who has
previously traded in Dwargon, is one of the goblins to
accompany him on the journey. So Rimuru used him as a guide,
and soon the two of them were in the Dwargon kingdom. Rimuru heads for the city
gates, leaving everyone but gobbled behind
because she doesn't want to start any trouble. There is a very long
waitin
g line at the gates. They are harassed by
some adventurers as they wait to enter. Rimuru decides to teach
the adventurers a lesson after they start fighting
by changing into a tempest wolf and roaring menacingly. The others in line in addition
to the bad adventurers are taken care of by the roar. When city guards arrive,
they throw Rimuru and Gobta into the dungeon. Gobta chooses to sleep
to pass the time. To Kaidou, the captain
of the guards, Rimuru explains who he is. While they are conversing
,
a different guard summons the captain, informing him
that a dangerous monster has been discovered in
the mines, seriously hurting several workers. Given what appears to be
a chance, Rimuru tells Kaidou to use a barrel
of healing potions he had brought for trading. Kaidou chooses to accept
Rimuru's gift, and when he comes back, he takes three
dwarves with him to show his appreciation for the magic
potions that saved them. After setting him free,
Kaidou decides to make amends by introducing Rimu
ru to
his older brother Kaijin, a capable blacksmith. Rimuru encounters the three
dwarves that his potion previously saved at Kaiju's
weapon shop, and it turns out that they all work here. Rimuru explains that his
village needs skilled craftspeople, but Kaijin
responds that he is currently overloaded at work. Minister Vesta gave him
an impossible delivery order to complete, but
he will still make every effort to complete it. Rimuru examines the one
sword that Kaijin had already made after realiz
ing that
the swords he is supposed to forge are made of the
same stuff that he was eating back in the cave. Using the resources already
present in the body of the great sage, it would be simple
to produce the entire shipment of swords all at once. As soon as the delivery is
finished, Kaijin and the three brothers go to a bar with
seductive elven hostesses to celebrate their achievements
before helping Rimuru. One of the elven girls
reads Rimuru's future peeking during the party,
revealing the pe
rson he is destined to be with. In the crystal ball, a
pretty girl who appears to be Japanese is visible. Vesta enters the scene and
starts a fight before they can continue discussing the girl. Kaijin becomes furious over
this and knocks Vesta out. requesting permission
from Rimuru to assist in his village. Rimuru gladly agrees, but
before they can leave, they are detained for assaulting
the minister and brought before the king for a trial. As a result, they are
not allowed to leave. It becomes
immediately
clear that Vesta had rigged the trial to make
it seem like Kaijin was to blame for everything. In response, king Gazel
speaks up and asks Kaijin if he is willing to
return to his service as he had been in the past. Kaijin declines, and
Myrd, Dord, and Garm are sentenced to years of
forced labor in the mines. letting him know that he had
already taken an oath to his new master, whom he had found. Gazel accepts his response
and changes the decision to exile everyone. As they are being
led from
the courtroom, Gazel speaks to Vesta and informs her that
due to her inability to be truthful and his actions,
he had to cut off contact with the slime who had given
them a healing potion that was more effective than
anything they could make. Vesta is let go by Gazel from
his position as the minister. Before leaving the city
with Myrd, Dord, and Garm, Kaijin bids his
younger brother farewell. One of Gazel's spies is
instructed to keep an eye on Rimuru by Gazel. Because that slime is a
t
rue monster and makes him think of Veldora, the three
explorers Elyun, Kaval, and Gido have just returned
from their mission in the kingdom of Blumund and are
in the process of informing Fuze of their findings
before being immediately dispatched on another mission. Due to Veldora's
disappearance, Fuze is concerned about potential
changes to the monsters in the vast Jura Forest. So, just as they are
grumbling about having to leave for another mission so
soon, he tells them to note anything out of
the ordinary. A mass girl named Shizu
approaches them and asks them to go with them to the forest. Elyun accepts the new
member of their small group with enthusiasm. The four dwarves who
traveled with Rimuru are using their artistic
talents in his village. The village reindeer's
reputation for training the goblins and fostering their
growth has spread throughout the forest, drawing numerous
other goblins from other goblin villages to his. He named each one, took
them all in, and was once more p
ut to sleep. Later, Rigur informs him that
they have seen some unsettling creatures in the forest. During his investigation,
Rimuru encounters the four Blumund explorers
who are being pursued by enormous monsters. Shizu battles them and
dispatches all but one, who is waiting behind her
and prepared to kill her. However, suddenly, a
black boss-level magic appears in the sky.
