As good as the first 13 episodes of VOTOMS have been, this OVA is my favorite of the series thus far. Exploring the war backstory of protagonist Chirico, Roots of Ambition is the most intense, most bloody, and most intriguing VOTOMS has been during this early stage of the franchise. The animation receives a noticeable upgrade, with gorgeous smoke effects and specific attention paid to the damage suffered in battle. Those battles are all meat-grinders more brutal than anything in the show; its mechs have never been this agile or this aggressive. The final confrontation in particular is a blood-soaked close-quarters war of attrition. Works as a gritty military-focused snapshot of the VOTOMS future, while also adding dimension to the series’ Chirico-Pailsen dynamic.
