Quick facts

Stage name: LEO. Born: September 8, 1998. BE:FIRST status: current member.

The roster label is dated through August 2026. Exact playlist cards preserve the lineup at the time of each video.

A distinct signature

Warm projection, connective performance energy and lyric participation that helps the group sound communal rather than assembled.

Watch a full phrase: preparation, attack, handoff and recovery reveal more than one center close-up.

THE FIRST foundation

The audition process treated singing, dance, rap and creative judgment as connected skills. LEO entered BE:FIRST with an individual history that the group format was meant to amplify rather than erase.

Competition footage is context, not a permanent personality diagnosis.

Seven-member video evidence

LEO appears in the 2023 “Mainstream” MV, the 2024 BE:FIRST × ATEEZ “Hush-Hush” MV and the playlist “Blissful” dance performance.

All seven then-members receive those three exact cards, including Ryoki.

Current roster rule

LEO remains in the official six-member lineup with SOTA, SHUNTO, MANATO, RYUHEI, JUNON and LEO.

Present status and historical participation answer different questions.

Voice, rap and movement

BE:FIRST avoid rigid permanent positions, so the useful profile tracks tone, cadence, movement weight, musical response and creative credits rather than assigning one narrow box.

Range matters when a performer can make different tasks feel intentional.

Collaboration routing

“Hush-Hush” belongs to BE:FIRST and ATEEZ, but the people remain members of their own groups.

A collaboration card records participation without inventing a merged identity.

Performance evidence

Live work exposes stamina, recovery, crowd response and how studio layers become a human arrangement.

One imperfect or spectacular night cannot stand in for the whole career.

Creative participation

Member lyrics, composition and choreography are tracked when credited, not assumed from branding.

Specific credit is stronger praise than a vague claim that everyone does everything.

Image integrity

This page uses a unique real official image stored locally with complete metadata.

The hub and three Reacts use different attachments.

RaeRae standard

Recognition should become easier after reading: follow LEO through rhythm, tone, interaction and the choices made outside the obvious center moment.

A profile is a listening tool, not a birthday card.

Career-file rule

Future solo, acting or collaboration work expands this page. It does not create a duplicate human.

One person, one canonical profile, many properly labeled chapters.
