HMS Little Formidable is preparing to sortie and she will grace your dock in the near future, Commander. She will be obtainable in the Big Lessons for the Little Lady event.
her seiyuu's probably still going to be Kugimiya Rie, the same as the OG Formi, complete with the "Tsundere Queen" voice, but I guess there was some scheduling problems on Kugimiya's part. Update: confirmed from this week's patch.
