Sources & verification

Mostly consistent; see notes. Checked 2026-10-02. Values the sources don't state are left blank.

Present on the Vengeance route per Game8's Vengeance Save the Students guide (Fionn boss strategy after the Eisheth fight) and a Vengeance stat block on the wiki (HP ~4,050 vs ~4,100 in SMT V). Samurai Gamers' Vengeance boss list omits him, so the position (between Eisheth and Yuzuru/Hayataro) is inferred. Light: wiki block says Null ('Expel=Null'); Game8's SMT V page says Resist - wiki value used.
