The thing that jumped onto No. 2 Division's escape vessel was a strange terraformar with strangely developed legs. It then takes the controls and tries to fly off with the escape vessel while everyone is still aboard. Yaeko and the others prepare for the worst as they're trying to figure out why it knows how to fly the vessel.
It submerges itself by storing air in the 
space between its wings and its back,
Er taucht, indem er Luft zwischen seinem
Rücken und seinen Flügeln speichert,
Se sumerge almacenando aire 
entre sus alas y su espalda.
Se sumerge almacenando aire 
entre sus alas y su espalda.
Il plonge après avoir emmagasiné
de l’air entre ses ailes et son dos,
Ele submerge, acumulando ar 
no espaço entre as asas e as costas,
