Battle Comrade is the main theme for Kurtis, and is also known as Tomo Yo
Tatakai ni Mi wo Sasage Aisae mo Sutesari Shinjiru no ha Ono re ga Kiba dake Aa Kodoku na Ookami
Kizutsukeru Koto no Kanashimi Shitta Toki Omae ga Soko ni Tatte Ita
Hiekitta Kokoro ni Atsui Kaze ga Kakeru Aa Senakaawase ni Katariau Yuujou
Senshi ni Yurusareta Tatta Hitotsu no Mono Inochi Kashite Tatakatta Nakama-tachi
Kakegae no nai Sen'yuu (tomo) yo
- Battle Comrade plays on the map Divine Prison the first time in Disgaea: Hour of Darkness, if you set the audio to 'Japanese' before entering the map.
- It also plays when Kurtis is summoned via Cell Phone in Disgaea 2: Cursed Memories.
- The song is also heard in Disgaea 3 when Prinny Kurtis is faced after downloading him via DLC.
- The Disgaea Custom Soundtrack refers to this track as My Comrade, which is a slightly more accurate translation of the original Japanese title, Senyuu Tomoyo. This version of the song also plays during Kurtis' appearance in Disgaea 4: A Promise Unforgotten.
