S1E119 : Konohamaru's Ninja Way

Konohamaru and Boruto set out again to rescue Remon but find they’ve arrived a little late. Soma has broken the seal and begins his resurrection. Boruto and Konohamaru try desperately to stop this, but none of their weapons and ninjutsu work against him. Watching them, Remon is inspired to carry out her vow and employ the method her ancestor used long ago to seal the monster.
