Stated by the author as “Daimajin” in a social media post

Jin Daima is an easygoing, opportunistic, and laid‑back student who belongs to the notorious weirdo group Kimengumi.

Despite his soft and gentle appearance, he has strong physical endurance and functions as an all‑rounder who can handle almost any role within the group.

He is defined by his personal motto “eat, sleep, rest,” and spends most of his day doing exactly that.

Academically he is near the bottom of his class, coming just above Rei Ichidou and Go Reiitsu in grades, but he shows little concern about this and lives at his own slow pace.

Middle School Years and Formation of the Kimengumi

During his first year at Ichio Middle School, Jin Daima is invited by Rei Ichidou to join a strange gathering of misfits.

Together with veterans Go Reiitsu and Kiyoshi Shusse, they officially form the perverted and eccentric group known as the Kimengumi of Ichio Middle School.

At the beginning, Jin and Kiyoshi Shusse get along poorly and clash often.

Kiyoshi dislikes Jin’s carefree attitude that “as long as there is food and sleep, life is happiness,” while Jin is annoyed by Kiyoshi’s chronic worrying, especially about being rejected in relationships.

Over time, both start to recognize each other’s quirks as personal strengths rather than flaws.

Their mutual understanding deepens, the friction between them fades, and they eventually build a close friendship strong enough that Jin’s parents come to deeply trust Kiyoshi.

High School Entrance and Repeating Years

Jin fails his high school entrance examinations and ends up repeating years twice.

After these setbacks, he manages to obtain an upgraded acceptance to a low‑ranking school called Hito-mazu High School, whose name roughly implies “for the time being” high school, emphasizing its low academic standards.

Soon after his admission, Hito-mazu High School merges with a prestigious preparatory school called Ousei High School.

Through this merger, the new Ichio High School is established, and Jin slides into Ichio High School as part of the reorganization.

At Ichio High School, Jin continues his laid‑back lifestyle but advances through the grades without major trouble.

He eventually graduates from Ichio High School along with the rest of the main Kimengumi members.

Post‑Graduation and Culinary School

After graduation, Jin decides not to immediately inherit his family’s cake shop, Daima Cake Shop.

Instead, driven mainly by the desire to “eat lots of delicious food,” he enrolls in a culinary vocational school.

Jin successfully completes culinary school, showing that when properly motivated by food, he can see things through.

However, he fails to hold down steady employment, wandering from job to job in his usual relaxed and unhurried fashion.

Even after graduation, he does not seriously commit to helping at his family’s cake shop.

He continues to live a carefree life focused on eating, sleeping, and taking it easy, just as he did in his school days.

Jin Daima is extremely gentle and good‑natured, coupled with a fundamentally optimistic outlook on life.

He is rarely seen angry, and he tends to flow with whatever is happening around him without resistance.

His daily life is dominated by sleep and meals.

He can easily finish a whole rice cooker’s worth of rice for breakfast and treats eating as the greatest joy in life.

Jin’s obsession with food is far from normal.

When his hunger reaches its limit, he is depicted as mistaking people around him for food and attacking them indiscriminately in a comedic, over‑the‑top manner.

When it comes to meals, he shows a surprisingly ruthless side and will not tolerate interference.

No matter who stands in his way, he is ready to punish anyone who disturbs his eating, revealing a cold and merciless facet that only appears around food.

Academically, he is careless and indifferent.

His motto “eat, sleep, rest” directly leads to his poor grades, placing him just above Rei Ichidou and Go Reiitsu from the bottom.

Despite being so leisurely, within the Daima family he is still considered part of the “hasty” type alongside his father.

This contrast highlights how relaxed the rest of his family must be, making Jin and his father seem relatively impulsive in comparison.

Friendship with Kiyoshi Shusse

Jin’s relationship with Kiyoshi Shusse is one of the more developed friendships among the Kimengumi.

They start out as near opposites: Jin is carefree and hedonistic, while Kiyoshi is anxious and constantly troubled by romantic failures.

Their clashing temperaments initially cause frequent arguments and mutual frustration.

However, as they repeatedly face daily problems and adventures together, each begins to acknowledge the other’s personality as valuable rather than irritating.

Eventually, they become very close friends, with Kiyoshi regularly managing Jin’s daily life, such as waking him up and making sure he gets to school.

Jin’s parents come to view Kiyoshi as a trustworthy companion, indicating the depth of their bond.

Relationship with Mai Fuchinoya

By chance, Jin meets a girl named Mai Fuchinoya, who is hospitalized in Ichio Hospital.

Their acquaintance gradually deepens into a significant and emotionally meaningful relationship.

The original manga does not clearly describe the final outcome of Jin and Mai’s romance.

Because of this ambiguity, many fan works and secondary creations have explored and expanded on their story, imagining various possible futures for the two.

Physical Strength and Stamina

Despite his calm and gentle look, Jin has excellent physical stamina and resilience.

He is not a specialist in any single area but can perform almost any role competently, making him a “balanced type” within the group.

Whether it is physical punishment, bizarre activities, or chaotic group missions, Jin manages to keep up.

His ability to maintain energy, especially when well-fed, makes him surprisingly reliable in demanding situations.

Eating Capacity

Jin is an extreme big eater whose appetite defines much of his character.

He can easily devour an entire large serving of rice right after waking up and is always ready for more.

His hunger can reach a point where reality comically blurs, and he sees other people as potential food.

These exaggerated gags emphasize just how central eating is to his life and humorously frame him as a “gluttony monster.”

Sleep Anywhere, Anytime

One of Jin’s signature traits is his ability to fall asleep instantly regardless of time or place.

Class, meetings, or even walking to school are no obstacles to his urge to sleep.

Once Jin falls asleep, waking him up is extremely difficult.

Because of this, he often relies on Kiyoshi Shusse to guide him through daily tasks like commuting to and from school, essentially functioning like a living alarm clock and caretaker.

Extraordinary Luck

Jin possesses remarkably strong luck, especially with random draws and prizes.

For example, he casually uses a vending machine with a prize system and hits the “winning” result dozens of times in a row.

This unnatural streak of good fortune is played for comedy and makes him something of a luck specialist within the group.

His luck often contrasts with his laziness, showing that life seems to favor him even without effort.

Impersonation Skills

Among the Kimengumi members, Jin is considered the most skilled at impersonating famous personalities.

He has a talent for mimicry and voice imitation, making him a versatile performer when the group engages in comedic skits or parodies.

This showmanship combines with his easygoing nature to make him a natural entertainer.

Whenever the group needs someone to imitate a celebrity or play a role in a comedy act, Jin is usually the first pick.

Jin comes from a family that runs a cake specialty store known as Daima Cake Shop.

The shop is respected enough that Jin is expected to eventually inherit it.

However, Jin temporarily puts off becoming the heir, preferring to attend culinary school to pursue his own interest in food.

This decision shows a rare instance of him actively choosing a path, even if his motivation is still primarily to eat delicious things.

His father Kyu, mother Jiyo, and grandfather Old Daima form a somewhat eccentric household.

Within this family, Jin and his father are both categorized as comparatively “hasty,” hinting at a comedic family dynamic where even the laid‑back Jin is seen as impulsive.
