The boy and the spirit away

Shuichiro, who has the unique constitution of being able to see spirits, was abandoned at a shrine when he was a child and raised by an old woman in the village. However, when Shuichiro grew up, his foster parent passed away, and he had to leave the village alone. He set off from the village in search of a new place, but then a spirit suddenly appeared. As he desperately ran to escape, he tripped and lost consciousness. When he woke up, there was a man dressed like a "Tengu"...!?
