Okay so basically Takemichi is depressed because of what he saw, who could blame him tho.
Takemichi can control how far in the past he wants to go, so he decides to save everyone for the millionth time
Takemichi is sick because of the overuse of his power. If he does it a few more times he could die. Takemichi does not care, because his friends are more important to him.
Hina is just his bff
