Tsukasa has learned about the cave where the nitric acid is collected. The race is on between Senku and Tsukasa to restore humanity in their respective visions.
The cherry blossoms we know, 
Prunus yedoensis, aren't self-pollinating.
.أزهار الكرز التي نعرفها، أزهار يوشينو، لا تلقح نفسها
Die Yoshino-Kirsche, die wir kennen,
ist nicht zur Selbstbestäubung fähig.
As cerejeiras que conhecemos, Prunus 
yedoensis não são autogâmicas.
Знакомый нам сорт, сомэй-ёсино, 
не может самоопыляться.
