Ni-Ki ENHYPEN Profile: Age, Real Name, Languages & Facts

Ni-Ki (Nishimura Riki) is the youngest member and main dancer of ENHYPEN, a seven-member K-pop group that debuted in 2020. Born December 9, 2005, in Okayama, Japan, he transitioned from a child dancer in SHINee Kids to a trilingual idol, often sparking curiosity about his unexpectedly deep voice and language skills.

Why is Ni-Ki’s voice so deep?

Fans often notice Ni-Ki’s unusually low tone for a young male idol. The explanation is straightforward: he was born in 2005 and underwent a natural adolescent voice change. As a dancer first—his pre‑debut training focused on movement—vocal training began only after his debut in 2020. No medical statement has been issued, but vocal coaches describe his range as a baritone that deepened with age, not a trained effect.

Voice change during adolescence

Ni-Ki entered I‑LAND at 14; his voice was still high. By the group’s first comeback, his pitch had dropped. This matches typical male puberty timing.

Ni-Ki’s vocal range and training

He is listed as a sub vocalist in ENHYPEN, but his parts often sit low. Company-provided materials do not claim any special technique behind his deep voice.

Can Ni-Ki speak fluent English and Korean?

Ni-Ki is a native Japanese speaker from Okayama. He learned Korean as a trainee under BELIFT LAB and speaks it confidently in group content. English is a work in progress; he uses simple phrases and occasionally relies on members or translators.

Ni-Ki’s English proficiency

Fan-compiled clips show him answering basic interview questions in English but hesitating on longer sentences. He often code-switches to Japanese or Korean mid‑sentence. No official test score exists.

Ni-Ki’s Korean language level

He is considered fluent, able to hold radio interviews and variety show banter without a translator. Kpop Been describes his Korean as “advanced” for a foreign idol.

Languages Ni-Ki uses in daily life

Inside the dorm, members report that Ni-Ki speaks a mix of Japanese and Korean. English is used mostly during international fan events.

Who is Ni-Ki closest to in ENHYPEN?

Ni-Ki has strong bonds with multiple members, but Sunghoon and Heeseung are frequently named as his nearest friends. The “YunKI” duo (Ni-Ki and Sunghoon) is a popular fan pairing.

Ni-Ki’s friendship with Sunghoon

They were seen together often during I‑LAND and continue to share a room. Sunghoon has described Ni-Ki as “playful and a bit annoying, but we’re close.”

Ni-Ki and Jungwon bond

Jungwon, the leader, acts as a caretaker for the younger members. Ni-Ki has referred to Jungwon as “like a big brother.”

Group dynamics and the ‘YunKI’ unit

The term “YunKI” combines Sunghoon’s family name (Park) and Ni-Ki’s stage name. They have performed unit stages together and often appear in same-frame selcas.

Ni-Ki (in a fan call, 2024): “I feel closest to Sunghoon hyung. We understand each other without words.” (ENHYPEN Wiki)

Who is the most flirty in ENHYPEN?

Fan opinions vary, but Ni-Ki and Heeseung are consistently named as the members who tease and engage in playful banter. No official ranking exists.

Fan perception of flirty behavior

Ni-Ki’s aegyo (cute act) and his habit of winking at cameras contribute to the perception. He also often initiates skinship with members.

Ni-Ki’s playful personality

During concerts, Ni-Ki will blow kisses to the audience or joke about dating fans. These moments are amplified by fancams.

Why is Lee Heeseung leaving ENHYPEN?

Rumors that Heeseung is leaving the group circulate periodically, but they are false. As of 2025, Heeseung remains an active member.

Origin of the rumor

A misleading YouTube video titled “Heeseung Leaving ENHYPEN” sparked the speculation. The video was clickbait without any official confirmation.

Official statements from BELIFT LAB

BELIFT LAB has not announced any member departure. ENHYPEN continues to release music and tour as a 7-member group.
