is this normal?

also when i was trying to make this i changed my name somehow, cant figure out how to change again, help?

That's Kaguya, as the name implies, a different npc partner that will assist you with certain features and combat.
To change partners back to Shizuka just hit alt, click story tab, partners, then select Shizuka and click summon.

lol im a fool, thanks for clearing that up ^-^
