The Shard of Tesla that caused the train incident is said to contain the notes for the Tesla Coil, and could trigger similar high-damage incidents in the vicinity. Botan and Kuruma act to recover the shard and prevent that, but are watched by another duo.
And it wasn't a battleship;
it was a destroyer escort.
كما أنها لم تكن سفينة بحرية
.بل كانت مرافقة مدمرة

fue un escolta de destructor.
C’était un escorteur d’escadre.
E não foi um navio de batalha,
foi um contratorpedeiro.
