Hello everyone~! This is Saori from VTuber Republic!

This time!! Four newcomers have formed a unit and made a dazzling debut! Their common trait is...... something quite rare among Nijisanji members: they’re a high school boy idol group!

Their first streams are already starting one after another! The four newcomers who debuted on September 17, 2025 — “Splare” have personalities that are way too strong!!

●Sumeragi Reo

A 17-year-old second-year student at Hoshino Academy.

The leader of “Splare,” who thinks he’s keeping everyone together! He’s in the dance club, loves rhinoceros beetles, and openly declared he wants to be a man like one.

● Shinomiya Yuno

A 17-year-old third-year student at Hoshino Academy.

The vice leader of “Splare.” With his soft-looking appearance and calm aura, he seems gentle at first glance...... or does he? He’s in the broadcasting club and is an outrageous big eater, having once eaten up to 197 bowls of wanko soba.

● Shirose Isumi

A 15-year-old first-year student at Hoshino Academy.

The youngest in “Splare,” who loves cute things and sweets. He’s in the tea party club (strictly as an eater). At first he seemed like an adorably cunning shota type, but turned out to be an unexpected yandere big-brother character.

● Hanakago Tsubasa

An 18-year-old third-year student at Hoshino Academy, who transferred from Osaka.

The big-brother figure of “Splare,” relied upon by everyone. He’s in the light music club, and in his desire to do something for the group, he bought land on the moon (???).

Their first streams have already begun, and each member is showing off incredible personalities you could never imagine just from their looks.

As expected of Nijisanji members! Some have already released singing videos, so they’re kicking off activities at quite a fast pace!

Welcome goods are also being released one after another~!

Everyone, please make sure to check out not only the newly arrived Splare members but also their future activities and interactions with their seniors!
