"Welcome to the world of science!"  When Yatori was 9 years old, she was sent to study with the general Bada Sankrein, and met a young boy her age, Ikta.  The world he shows her is new and exciting, like nothing she's ever seen.
I'll never completely become a blade.
.فلن أصبح سيفاً أبداً
werde ich niemals eine
vollwertige Klinge sein.
jamás me volveré
una espada por completo.
jamás seré
una espada por completo.
je ne me transformerai jamais
en une épée sans âme.
non diventerò mai del tutto una lama.
nunca serei completamente
 uma espada.
стать полноценным клинком мне и не светит.
