Career

Aogiri High School started on October 27, 2018, with Otodama Tamako and Minazuki Natsuki as its first members. The two formed the Game Club of Aogiri High School as a duo of high school student characters. Their content was mainly produced skits and game videos. The pair released their first joint video on November 11, 2018, and did their first crossover with the members of the main Gamebu channel on January 27, 2019. Tamako was the first Game Club member to debut, and in her early appearances she played Super Smash Bros. as the Pokémon Lucario.

In February 2020, members of the group began receiving their own YouTube channels. Tamako's channel was created on February 8, 2020, followed by channels for Natsuki and Ishikari Akari later that month. Tamako held her first solo stream on February 12, 2020. Its title asked viewers what she should do. She was the first in a line of solo debuts that later included Yamaguro Nekuro, Minazuki Natsuki, Ishikari Akari, Kurikoma Komaru, Oshiro Mashiro and Chiyoura Chiyomi.

She has stayed active with the group since then. In June 2025, her channel reached a new milestone. To mark it, commemorative merchandise went on pre-order through viviON BLUE, including a character art print, acrylic panels and mouse pads.

Activities

Streaming style

Tamako opened her solo channel with a chatting stream and then played Ring Fit Adventure as her first game. She has since played Animal Crossing: New Horizons, Slither.io, Mahjong Soul, Gartic Phone, KUUKIYOMI and Fall Guys, along with horror and observation games and viewer-participation sessions. She also streams late-night free talk regularly.

Besides gaming, her channel offers ASMR streams, a recurring sing-along series and live-action videos. Some of these focus on ramen, which she enjoys introducing to viewers. Others include off-collaboration meals with other members. Her 3D model has allowed her to take part in 3D content as well.

Music and works

Her first song cover was "Compared Child," originally by TUYU.
She hosted a karaoke stream dedicated to Nightcore songs, which drew wide attention to her channel.
She runs a recurring sing-along streaming series on her channel.

Characteristics

Tamako's character has purple hair. Her content mixes gaming, music, ASMR and live-action segments, which reflects Aogiri High School's playful motto that anything goes as long as it is fun. As one of the two original members, she is closely linked to the group's early history and the Game Club format that came before its individual channels.
