Mitsubishi Suicide has been played on NTS shows including Enter the Noid w/ Ringtones, with Song for Ciara H first played on 24 February 2023.

Mitsubishi Suicide are a screamo band formed in London, England in 2021, initially comprising of Aidan Ostermaier (bass), Malachy O'Neill (guitar) and Hal Hewetson (drums). They released their first single 'Song for Ciara H' in November 2022, with the self-titled debut album 'Mitsubishi Suicide' following in February 2023.

After the release of the album, the band would release three more tracks with the original lineup, two featuring on the This Desirable Plot single in November 2023 and one on the Fourths split with Bright Little Stars, Burial Etiquette and Glowwworms in December 2024.

The band was announced to be playing Manchester's Outbreak Festival in 2025, but ultimately pulled out. Aidan would leave the band that same year, with the 'For the Last Toll' EP only being attributed to "h,m,"

Malachy is active solo as xmal and plays in the post-punk duo Most Things. Hal currently performs solo as 300SkullsAndCounting.
