聖者無双 [Seija Musō]

A light novel adaptation from Kōdansha that began in 2017, Seija Musō follows a salaryman reincarnated as a healer in a fantasy world, where he discovers his support magic is far more powerful than expected. Spanning 16 issues, the series is best known for its blend of isekai tropes and unconventional combat, with the protagonist using his healing abilities in clever, battle-oriented ways. It stands out for its fresh take on the "support class" archetype, making it a notable entry in the crowded isekai genre.
