[Research Subject Individual Record]

Classification: Harvest Mouse Beastman Individual ID: KM-01 Gender: Unknown (Adult) Total Length: Approx. 10cm Weight: Approx. 18g

■ Physical Characteristics

• Fluffy, light brown hair
• Round, upright ears
• Large black eyes
• Short limbs
• Extremely soft and squishy physique, especially around the cheeks and abdomen
• Possesses brown fur resembling a romper

■ Habitat Primarily inhabits grasslands with tall grass or riverbeds. Constructs spherical nests woven from dried grass and plant leaves, living inside them.

■ Diet

• Mixed feed for small birds
• Various plant seeds
• Pellets for small animals

Confirmed to prefer the above.

■ Behavioral Traits Extremely timid and cautious. Observed to cry and wail frequently when encountering unknown environments or large creatures.

Conversely, possesses high mobility using plant stems, proficient in vertical climbing and moving between thin stalks.

Often observed floating while wedged between plants due to light body weight.

■ Language Ability Possesses language skills sufficient for communication with humans.

However, due to the structure of the vocal organs, there is a significant lisping tendency.

Example: "Arigatou" (Thank you) ↓ "Aigato"

"Daijoubu" (It's okay) ↓ "Daijo-bu"

Resulting in infantile pronunciation.

■ Reproduction and Child-rearing The observed individual is currently raising three infants.

Infants are approx. 3cm in length. Appearance is a miniaturized version of the adult.

This species possesses an extremely strong nurturing instinct, which is particularly prominent in subject KM-01.

• Constantly pulling infants close
• Frequent cheek-rubbing
• Giving priority to infants during feeding
• Shielding infants immediately upon sensing danger

These behaviors have been confirmed.

■ Special Notes Subject KM-01 shows a significant doting tendency toward its offspring.

Attachment to the infants is extremely strong, with many recorded statements such as:

"My babies are the cutest in the whole wide worwd." "Lookie, lookie! Aren't my babies amazing?"

Recognized among researchers as a "doting parent," but has a high success rate in rearing and is deeply trusted by the infants.

Requires careful handling during observation, as separation from the infants causes strong anxiety reactions and wailing.

[Research Subject Infant Record]

Classification: Harvest Mouse Beastman Individual ID: KM-01A to KM-01C Gender: Unknown Total Length: Approx. 3cm Weight: Approx. 2-3g

■ Physical Characteristics

• Fluffy, light brown hair
• Round, upright ears
• Large black eyes
• Short limbs
• Extremely soft and squishy physique
• Possesses brown fur resembling a romper

Appearance is a miniaturized version of adult individual KM-01.

■ Developmental Stage Equivalent to a human infant at the time of this record.

Independent walking is impossible; only the following have been confirmed:

• Belly crawling
• Crawling on all fours

Running and jumping behaviors have not been observed.

■ Language Ability Communication via language is impossible.

Vocalizations consist primarily of cries and babbling.

Confirmed vocalization examples:

• "Au~"
• "Yat!"
• "Chiu..."
• "Kyuu..."
• "A-u!"
• "Pyat"

Vocalization frequency increases significantly during interaction with adult KM-01.

■ Diet Receives feeding from the adult.

Primarily consumes finely crushed:

• Mixed feed for small birds
• Seeds
• Pellets for small animals

■ Behavioral Traits Extremely curious.

Shows interest in surrounding plants, dried grass, and pebbles, actively trying to touch them.

However, also very cautious; will immediately approach the adult in response to:

• Loud noises
• Sudden vibrations
• Unknown individuals

■ Dependency on Adult The most prominent characteristic of the infants of this species.

Subjects show strong dependency behavior toward their guardian, KM-01.

When the adult is within sight:

• Active behavior
• Frequent vocalization
• Expressions resembling smiles

When the adult disappears from sight:

• Loud wailing
• Shedding tears
• Becoming unable to move from the spot
• Huddling together

These panic reactions occur. The phenomenon of all three individuals crying simultaneously is referred to by researchers as "chain crying."

■ Sleep Behavior Sleeps in close contact with one another inside the nest.

Frequently observed sleeping in a clump around the abdomen or arms of the guardian KM-01.

■ Special Notes The subject group possesses very high sociality.

Observed behaviors among siblings include:

• Sleeping together
• Crying together
• Playing together

When the guardian KM-01 returns to the nest, all three individuals have been confirmed to approach at once, attempting to cling while making vocalizations such as:

"Au-!" "Yat!" "Chiu-!"

Researchers have given them nicknames such as "Pre-walking Fluffballs" and "The Three Crybaby Brothers."
