Im look for a manga that i read... it is about a man, an adventurer, who finish all the request and decided to have a vacation. While he was eating out side, his onigiri (i think) fell so he run to catch it because it roll until there is a hole where he fell unto another world. There he meet beautiful elf who was chasing by man (soldier i think) and she save her while he kill also a dragon(who was sleeping and woke up because of commotion). Then the village this elf lives was on famine and many was sick so they need foods and medicine where the men gave the meat (from dragon) and all of his potion... when he came back to his two roomate (girls) was waiting for him. One is originally a dragon and the other is a slime ithink...

I forgot the name of this manga but it is about a old (or older) man and he is an adventurer who got his vacation and while he was eating his onigiri fell. He run to it but he fell into a whole where another world lies... he meet an elf girl who was chase by two soldier and he save her from them. But the village of the elf was on famine and many was seek so that is why they need potion to heal those sick. Before the man return to his world (by a pearl?) He gave them meat (from a dragon) and gave all of his healing potion. When he got back he has two (girls) roomate, one is a dragon and other is a slime i think...
