Type-Moon, but the Servant is Tom

Bai Song, 18 years old, seems to be a traveler.
After Bai Song was killed by a mud truck, he found himself transported to another world, and he even had a panel that could summon Servants.
Before Bai Song could feel happy, he suddenly realized that he seemed to have crossed over to the Type-Moon world.
Moreover, it was at a time point under the pen of Gen Urobuchi, the warrior of love.
Bai Song smiled wryly.
“If I commit su*cide now, I should be happier, right?”
And then…
Looking at the summoning formation, he saw a blue-gray large cat holding a trophy that read “National Rat-Catching Champion.”
Bai Song suddenly realized that the Type-Moon world had become much less terrifying in an instant.
