My Superpower Is a Heroic Spirit Training Simulator

Xing Jian died, but awakened a supernatural ability that can only be obtained after death, called the Heroic Spirit Raising Simulator.

But instead of raising others, he gets summoned and raised by his Master.

As their affection and bond deepen, Xing Jian can choose to exchange for or draw skills and Noble Phantasms belonging to Heroic Spirits from Type-Moon.

The data and class he gets with each summoning are random. In other words, it's all down to luck, and it seems that the Master's luck plays a part too.

Xing Jian: We've already done a Heroic Spirit Summoning, so why isn't there a proper magus here? Give me more mana! Do I really have to get in there myself and replenish the mana?

Each summoning seems to take him to a different worldline.

First playthrough: On a rooftop, Xing Jian and his newly appointed Master stare at each other. In the end, they decide to jump off together.

Xing Jian: Nobody understands Heroic Spirits better than I do!

Second playthrough: A little guy in bandages orders him to kill himself. Magic Resistance A, Command Spell fails.

Xing Jian: I love how you can't stand me but can't do anything about it.

Third playthrough: His Master is an old man who's nearly in the grave. The man almost drains all his life force on the spot, so Xing Jian has no choice but to bind himself to another mana-supplying tool.

Since his Master is no good person, he decisively chooses to stab him in the back.

Fourth playthrough: Xing Jian sees the bandaged kid again, but this time he's an adult. To his surprise, the other man acts completely out of character and clings to him all gooey and affectionate, scaring Xing Jian into immediately turning into spirit form.

Fifth playthrough: This time, his Master has long black hair and wears a knit cap, but his moral standards leave much to be desired. Xing Jian vehemently condemns him for trying to fake an accident for compensation.
