[Genshin Impact] Socially Anxious Tartaglia

An antisocial shut-in transmigrates in the guise of a young master and unexpectedly gains the ability to summon new companions through a System!

A huge crossover mashup.

How do you tell who's stronger when everyone's power system is different? Have a fight and find out!

The writing is really bad, elementary school level (no writing skills).

Just an ordinary person wearing Tartaglia's skin, with a few of his traits inherited.
