Alright... Hey you, high-school boy.
I, the great Hououin Kyouma, of whom even the gods are jealous, will give you something nice.Okay?It's a device that measures the rate of change between diverging worlds.
"Diverging worlds" is my take on the kanji for "world-line" with furigana for "divergence" in English above it.Huh..? But this is...Don't be so anxious. Your world has a guy like me too, right? A time traveler who wants to save someone precious who died?Give it to that guy. And then you can tell him, "Good hunting".
"健闘を祈る" (kentou o inoru), literally "pray for a good fight". Commonly used before sports matches and the like.Er.. Well, no.. That guy's kind of my enemy, you see...I don't want to, 'cause Fujiwara's one of our enemies... so...Hold on a second here. You're telling me that a guy who would go so far as to seek out the power of a goddess with supreme power over space & time to save his older sister is...an enemy?...yeah...And the guy, you said, whose entire reason for looping through time was just because a sexy bombshell asked him to... is the protagonist? i.e. you?...That's correct.......Eh?
