The Crimson Schooltrip episodes will have a new OP theme and a "main theme", probably used as new ED.
Both will be sung by Kuraki Mai, who'll have a cameo in the episodes too.
OP song:
「きみと恋のままで終われない いつも夢のままじゃいられない」
"Kimi to koi no mama de owarenai itsumo yume no mama ja irarenai"
"It won't end as love for us, it can't be a dream forever"
Main theme:
「薔薇色の人生」
"Barairo no jinsei"
"Rose-colored life"
