I think it should be "fewer friends" (countable), not "lesser friends" (which actually makes Itsuki sound way more arrogant if he judges friends on a scale LMAO).
"Do you have fewer friends than me?" Could be interpreted as "You don't have as many friends as I have?"
"Do you have lesser friends than me?" Could be interpreted as "You have friends that you think less of than you think of me?" which fits the dirtbag Itsuki.
And now he's going to misinterpret his newest "vision" and cause more uneccessary havoc.
I've often seen “less” used where the word should be “fewer”, but this is the first time that I've seen “lesser” used where the word should be “fewer”. [ul]“few” = “not many”
“fewer” = “not as many”
“less” = “not as much” (Use “little” for “not much”.)
“lesser” = “inferior”[/ul]
