This is such a bittersweet story.. When Hikaru B does everything he can for Torao despite being bad at them and getting scolded.. When Hikaru B protected Torao from the poisonous sandstorm in the desert.. When Torao slept for another 250 years and Hikaru B just waited for him at Oze and built a house for them to live in.. When Hikaru B wanted to be a human just so he could hallucinate and hear Torao... Wonderful story!!
