Kabaneri of the Iron Fortress Season 1 Episode 6

Gathering Light

The Kotetsujyo is standing before a giant cluster of Kabane, the Black Smoke, and all seems hopeless. Meanwhile, Ikoma and Mumei find themselves at the bottom of an abandoned station. Surrounded by Kabane, Mumei buried under rubble, and no backup in sight, the situation is dire, yet Ikoma still somehow stands forward to face it.
