Miraculous Revival! Cosmo of Friendship

Andromeda battles against Unicorn Andromeda uses his chains to form a nebula chain (Andromeda Galaxy). Unicorn runs directly to Andromeda but his chains attacks Unicorn, thus impoosible for Unicorn to attack. He tried to attack Andromeda from the air but the chains still attack him in the air. Suddenly, the chains set a reaction and form a code for Andromeda. He wonders what is could be until at the end, his brother appears.
