The real hikaru has died a long time ago, but what happened in this chap is that the fake hikaru/entity has saved yoshiki from death, and yoshiki explained to the real hikaru that he wants to live now bc someone is waiting (akw: yoshiki likes the entity and wanna live with him) so he's alive with the entity

Ok thank you
