If Kewl tune raises all my levels by 3 and i have a raidraptor- noir lanius lvl 7 and target it with pain Lanius. which level has the pain lanius 7 or 10? and if i then use the grave effect of noir lanius to increase by 1 which is the new level?

Pain Lanius:

"You can target 1 "Raidraptor" monster you control that has a Level; take damage equal to its ATK or DEF (whichever is lower, but your choice if tied), and if you do, Special Summon this card, and if you do that, this card's Level becomes the current Level of the targeted monster."

Noir Lanius:

"You can banish this card from your GY; increase or decrease the Levels of all "Raidraptor" monsters you currently control by 1."
